Mounting Media without DAPI
After the immunofluorescence protocol, samples should be mounted between slide and coverslip for microscopy analysis. For this, it is necessary to use a suitable fluorescence mounting medium in order to fix the samples on the slide and prevent their dehydration. In addition, the mounting media increase the index of refraction.
Some mounting media contain additives such as DABCO, an anti-fading agent that protects the sample against photobleaching. Depending on the fluorochromes used, some anti-fading agents are more effective than others. In addition, there are also mounting media containing DNA dyes (such as DAPI). Thanks to these mounting media, it is possible to color the cores during assembly.
There are mounting media capable of polymerizing, these media are very widely used for fluorescence microscopy. Thanks to these mounting media it is possible to keep the samples for a long time if they are protected from light, the only factor determining the shelf life is the fluorochrome used whose fluorescence intensity decreases with time.

Dr. Thomas LoBue and the team at LoBue Laser & Eye Medical Centers believe it is important to invest in technology and equipment that makes treatment safer, more precise and more effective for our patients. No expense is spared when it comes to the safety and comfort of our patients as we improve their eye health and vision. The following is a sample of the technology we offer at our practice.
Laser-assisted and ORA-Guided Cataract Surgery
Dr. LoBue uses laser technology to enhance the safety and precision of cataract surgery. The advanced femtosecond laser replaces handheld surgical tools for many steps in the cataract fragmentation and removal process. It creates clean incisions to access the cataract-diseased lens that are more likely to heal without complications. Then the laser softens the lens before fragmenting it into small pieces; this requires less energy than the ultrasound energy used in traditional cataract surgery, making this step of the procedure less risky.
Other forms of technology are also available for a fully customizable experience. For example, prior to surgery, integrated optical coherence tomography (OCT) is used to capture high-resolution images of the eye; this information is then used to plan and perform surgery to the exact specifications of the patient. The ORA system provides continuous optical status throughout the procedure, making astigmatism correction and lens implant power more accurate. The Verion image-guided system helps Dr. LoBue take the pre-operative images he needs, then plan out the procedure and guide him during surgery.
ORA – Intraoperative Astigmatism and Intraocular lens calculation.
PanOptix and Toric Lenses
After a cataract has been successfully removed from the eye using the advanced technology described above, the lens is replaced with an intraocular lens implant (IOL). The better and more advanced the IOL, the less dependent the patient is on glasses after cataract surgery.
Dr. LoBue offers a variety of vision-restoring IOLs, including the PanOptix trifocal IOL, which enables clear vision and enhanced image quality at virtually any distance. Another option is the toric lens for correction of astigmatism.
Optical Coherence Tomography (OCT)
In addition to its use in cataract surgery, optical coherence tomography or OCT is also used by Dr. LoBue in the management of glaucoma and other retinal diseases.
Not all of Dr. LoBue’s technology is designed for cataract patients. He uses state-of-the-art optical coherence tomography (OCT) to actively manage glaucoma and other retinal diseases. The system allows the doctor to take high-resolution cross-section images of the biological structures of the eye to detect problems and monitor progression of the disease.
Corneal topography is a diagnostic tool that produces a detailed, three-dimensional map of the surface of the cornea. The information obtained by the Pentacam corneal topography system is used to understand the shape and power of the cornea and to help diagnose, monitor and treat a number of eye conditions. Corneal topography is also useful when fitting contact lenses or planning laser vision correction.
Endothelial Cell Count
The cornea, or clear covering of the eye, is lined with special cells known as endothelial cells. Adequate endothelial cell density is required for any patient seeking treatment with phakic intraocular lenses or implantable contact lenses for refractive errors. Using specular microscopy technology, Dr. LoBue can check endothelial cell density pre-operatively and monitor it periodically following implantation of the artificial lenses to ensure the continued health of the endothelium.

Induction Chromatique Serie B 4/4
100 x 100 cm
Chromatic Inductions are closely related to the phenomenon of post-image, which is also known as the retinal persistence effect. This means that if a viewer stares at a red plane briefly and then looks away, the retina preserves the image for a few seconds, but the image appears green, which is the induced color or complementary color.
These phenomena occur separately, one after the other; Chromatic Inductions, however, reproduce them all at the same time. They therefore manage to stabilize—and render visible—a phenomenon which can only be captured fleetingly and in very special circumstances.
Further to his experiments with the phenomenon of retinal persistence, Cruz-Diez also produced Douche d’Induction Chromatique [Chromatic Induction Booth] in 1965 and Induction à double fréquence [Double Frequency Inductions] in 1986.

Volvo has funded a startup that could transform car windshields in to massive heads-up displays.
Through its venture capital arm, Volvo Cars Tech Fund Venture Capital, the Swedish automaker invested an undisclosed sum in optical and imaging tech firm Spectralics.
Israeli startup Spectralics created what they call a multi-layer thin combinationr (MLTC). It’s a film that can be applied to transparent surfaces—like windshields.
Volvo claims that the MLTC films allow images to be projected onto walls, creating a larger head-up display with virtual objects layered above the actual windshield view. It could allow for a more immersive experience than the existing augmented-reality head-up display we have seen in 2021 Mercedes-Benz S-Class.
Volvo Concept Recharge
Volvo indicated that other uses could include in-cabin sensing filters and projections from forward-facing cameras, to lessen blind spots.
Volvo has not discussed when the technology may be available for commercialization or whether it will ever see production cars. An investment may be the first step in a more long-term relationship that might see Volvos with MLTC tech in the future.
The automaker invested previously in Silicon Valley-based lidar startup Luminar and announced in 2020 that roof mounted Luminar lidar sensors would be included in its production vehicles starting in 2022. Based on the SPA2 architecture, the first vehicles to receive lidar technology will be produced.
Volvo stated that the next generation XC90 would launch SPA2 in 2022. The automaker confirmed the electric XC90. However, gasoline-powered hybrid and plug in hybrid powertrains will likely continue.

The survey of dual wavelength crystal lasers is introducted in this paper. Our research results on dual wavelength crystal lasers are described mainly. These are as follow:oscillation condition of a simultaneous multiple wavelength laser has been established and used to analyze the possibility of simultaneous oscillation in various neodymiumhost crystals,such as Nd : YAG, Nd : YLF, Nd : BEL and Nd': YA103(YAP) crystals at transitions from ~4F_(3/2)—~4I_(11/2) and ~4F_(3/2)—~4I_(13/2). It shown that this kind of laser can be realized in all the described crystals in a pulsed state. In general, continuous wave operation, however, can only be achieved in Nd : YAP crystal. On the basis of these results, the CW dual wavelength crystal lasing has been achieved for the frist time by using Nd : YAP crystal.The output power of 1079.5 nm and 1341.4 nm was 23.9 W and 25. 4 W respectively.The Nd : YAG and large energy Nd : YAP dual wavelength pulsed lasers were also acquired. The experimental results show that the temporal and spatial overlops of both beams were quite good for both lasers. In addition, we has obtained 1655 nm and 1663 nm dual wavelength and 2711 rim, 2730 nm and 2795 nm three wavelength Er : YAP lasers.

HomeScope is a digital system. Its brain is a Linux operating system running on a Raspberry Pi computer (RBPi) which is in conversation with two Arduino micro-controllers which are configured as two-state automata; i.e. they can be listening to or executing RBPi wishes. These wishes are transmitted via a custom pin protocol (2 bits per degree of motion) which can be set using the wiring Pi library to read and write to the RBPi GPIO pins.
HomeScope robotic capabilities (XYZ movement) are used to focus (Z axis) the image/video capture plane (image sensor) of the RBPi camera into a plane within the biological texture living within HomeScope’s cell culture and to scan (XY axes) its spatial distribution. Focus and spatial scanning wishes are executed by the Arduino systems: Arduino Z controls a stepper motor via EasyDriver control and use it to focus on the sample. For direct interaction with a user, two Push buttons are hooked to the Arduino. Arduino XY controls the PlotterBot Tiny CNC micro-robot holding our biological sample to scan it by taking image captures at different spatial locations. A user can interact with the CNC system directly via a Joystick and read its servo coordinates via a LCD display.
An optical system, consisting of an optical tube, one objective, and a focal lens needs to be aligned with the Illumination system for magnification of the sample. A single white LED light which is connected to the PWM pin of the RBPi as well as to a potentiometer to control the illumination system. For fluorescent microscopy, a UV LED must be added to the illumination system, while also using anti-UV coating of the focal lens to protect the camera sensor. A RBPi Camera (image) sensor is located at the focal plane of the optical tube and it’s used to capture images and video.


Eye Surgical treatment has actually become a mainstream approach of vision correction, as well as this write-up will explain the advantages as well as disadvantages of three different approaches being provided to the clinical customer.
Lasik Eye Surgery
LASIK is the acronym for Laser-Assisted Sitting Keratomileusis and also is an eye surgical system which completely deals with vision by getting rid of a thin layer of the cornea. This procedure works best on clients with modest to high levels of nearsightedness (nearsightedness), low to moderate degrees of hyperopia (farsightedness) and astigmatism related to nearsightedness, and that have thick corneas. It is one of the most well-known surgical vision modification approach.
People with regular eye view see objects clearly because images are brought right into a proper prime focus by the cornea and also lens of the eye. Preferably, the cornea's curvature is equally matched to its length in a normal eye. Individuals with astigmatism, myopia or hyperopia have off-and-on shaped corneas, so the items seen are not concentrated properly. LASIK changes corneal shape by accurate removal of corneal tissue, and also by doing so remedies the eyes' focusing power.
There are, nevertheless, threats to LASIK eye surgery.
There is a remote chance of full loss of vision. If this takes place, it is generally because the client had a pre-existing condition which must have precluded the surgery in the first place, such as pregnancy, cataracts, joint inflammation, diabetes, glaucoma, or lupus. Individuals with huge pupils are additionally inadequate prospects for LASIK. Dry eye disorder will be intensified by this procedure.
A few clients complain that they completely see "ghost" pictures, have blurred vision, decreased contrast as well as poor night vision. When LASIK wased initially introduced, 5% of people had post-operative grievances; nonetheless, refinements in the procedure have actually created this rate to drop to less compared to 1% if LASIK is carried out by competent experts and individuals are effectively evaluated prior to surgery. If issues do happen, they could usually be resoved by a retreatment.
FDA has approved LASIK laser eye surgical treatment given that 1998. While there are a great deal of satisfied clients, there are nevertheless no long-term research studies concerning its results. Recognize the limitations and the risks of LASIK eye surgical treatment before you sigh up for the procedure.
Though less well known, these little implants could enhance vision in individuals with moderate to modest myopia without the danger of long-term eye damages intrinsic in the tissue removal method of LASIK. Intacs are semi-circular disks implanted in the cornea which stretch it to think a flatter shape. Though a little much less specific compared to LASIK, they are removeable and also changeable, so if the patient has an unanticipated over- or under-correction, the dental implant could be eliminated and an additional of a different size inserted to acquire the wanted improvement. The implants lie at the edge of the cornea, so the central aesthetic location is entirely undamaged as well as undamaged, and also the stamina of the cornea is undiminished, making it a much better choice for pilots and those that participate in get in touch with sports where eye injury is an opportunity.
Intacs disagree for serious myopia and also more than small astigmatism (1.00 diopters), as the cornea could just be extended up until now. If the Intacs are removed, vision returns to its preoperative degree. In addition to vision improvement, Intacs are additionally made use of to deal with keratoconus.
Intacs are FDA accepted as well as One Decade researches have actually disclosed no significant troubles with Intacs and also few patient complaints; nonetheless, since the procedure takes extra training than LASIK, there are fewer eye surgical procedure centers using it. However, the Intacs website gives a checklist of professionals in each state, also a few in Canada, Europe and also Mexico.
Because many individuals do not want to take the chance of LASIK as well as Intacs could not assist those with severe vision issues, intraocular lens implants (IOL) are a brand-new choice approved by the FDA in 2004 to remedy moderate to extreme nearsightedness. The Craftsmen lens, manufactured by Ophtec, resembles the kind of lens implant made use of to recover vision adhering to cataract eye surgical procedure.
The new IOL, called the Craftsmen, is intended for just patients that have 2.5 diopters or less of astigmatism.
The fabricated lens does not replace the natural lens, yet is inserted before it. The main issue found with the implant was the steady loss of endothelial cells in the corneas of individuals that got the implants. The endothelium is a layer of cells that line the undersurface of the cornea and also are vital in keeping the cornea clear. A three-year research study revealed a consistent steady loss of endothelial cells of 1.8 percent a year. At this moment, no person could predict whether this loss will certainly continue at the same rate forever, and even its influence on corneal function.
To decrease lasting results of the device on the corneal endothelium, the FDA is requiring that the new lenses be identified to specify that they ought to only be implanted in people whose corneal endothelial cells are thick adequate to stand up to minor cell loss.
Much more serious problems were couple of: retinal detachment (0.6%), cataract growth (0.6%), and also corneal swelling (0.4%). The FDA is needing Ophtec to carry out a five-year follow-up study of its implant clients to that site better analyze the post-surgical incidence of cataract advancement, retinal detachment as well as other ocular illness.
The Artisan lens is meant to be an irreversible implant.Though it can be removed surgically, vision might not always return to exactly what it was prior to getting the lens. Since it does not impact astigmatism, individuals visite site with this issue may still need glasses.

Round Infinity Tunnel Light and Mirror
The Infinity Mirror is on another level compared to normal mirrors. It’s a stunning talking piece that’s also perfectly usable as a normal mirror for everyday use.
An Infinity Mirror contains two mirrors with different transmissivity and reflectivity, that combine to create the illusion of infinite space. The surface at the back of the Infinity Mirror is 100% reflective – exactly like an everyday mirror – but the front surface is only 50% reflective and therefore casts back about half of the light that hits it. This means that some of the light escapes through the front mirror and into your eye. The rest is bounced back off the rear mirror, then into the front mirror again, and this process continues off to infinity – hence the name.
When you sandwich strips of LED lights (42 in this case) between the two mirrors, a little bit of light escapes each time and each successive LED will look a little bit dimmer until they gradually disappear. The Infinity Mirror is a great visual stimulant that can be used in everyday life and is guaranteed to make anyone look ‘out of this world’.
The mirror is 23cm in diameter.
Requires 3 x AA batteries (not included).
Can also be used with an AC adaptor (not included).

SINAR COLOR CONTROL Filter
Professional filter technique
Even with sophisticated scanners and process techniques the printed reproduction of a photograph can only be as good as the image supplied by the photographer.
Controlled subject brightness range, established by careful spot exposure readings in the film plane is just one aspect. Equally vital is professional colour control for a specific impact. The result the client gets should need no further explanation – it must make its point in creative content and technical perfection.
Denis Savini’s filter expertise
A masterful application of the SINAR COLOR CONTROL filter system is Zurich photographer Denis Savini’s fruit still life.
The shot involved four separate, carefully planned exposures, based on detailed readings with the SINARSIX Digital exposure metering system. The working aperture was set at 1/22.
Savini started by meticulously arranging the still life subject itself, lit it carefully and used the movements of the 8 x 10″/18 x 24 cm SINAR p2 for precise sharpness distribution control. The first exposure recorded the blue shaded background. For this, Savini evenly lit a white wall and achieved the shaded effect with a graduated blue filter. Thanks to the large filter movement possible in the 125 mm filter holder, the photographer could adjust the graduation to his precise requirements. In this ingenious filter mounting you can freely rotate the filter to run the graduation at any angle to the image edge. The system even takes two graduated filters of different colours, displaced against each other.
Savini controlled the power of the flash illuminating the background to allow an exposure at a constant working aperture (1/22) used for the first three part exposures. The fluorescent tubes and the foreground flashes were switched off for this exposure.
Matching the film’s colour balance
The second exposure was the subject itself, with the background lighting switched off. Savini used a CC1 OB colour correction filter (blue of 0.1 density) for colour balance matching, to correct the slightly yellowish film rendering. A preliminary exposure test established the filter required for the emulsion in use.
The closely spaced CC filter steps in the SINAR COLOR CONTROL filter range are ideal for this as they cover densities down to 0.025 in every colour.
Special light correction
The third part exposure of 8 sec at the same working aperture was solely for the fluorescent tube in the background. The discontinuous mixed spectrum of fluorescent lighting usually calls for initial tests. These involve a reading with a colour temperature meter, followed by an exposure test on the film, at the intended exposure time and with the filter combination suggested by the reading. For the blue/red balance the colour temperature meter indicates a reddish or bluish conversion filter, plus a green or magenta CC filter to correct the green band of the tube emission. Savini’s readings and tests suggested an 81 C conversion filter plus a CC15M correction filter.
Incidentally, in the SINAR COLOR CONTROL filter system there is no need to combine CC10 and CC05 filters for a 0.15 density – all colour sets include a CC15 filter.
The star effect
The final step was the star exposures. For this, Savini marked on the 8 x 10″/18 x 24cm ground glass screen all the locations where he wanted the stars. To superimpose the stars, he first drilled a tiny hole in a thin black metal plate and placed this directly in front of the concentrated beam of a conical lamp head. This is easier still with the bellows hood mask 2 whose four roller blinds can be closed down to form a square aperture of any required size anywhere in the image area. The camera was then set up in the light axis and adjusted to make the illuminated hole appear at the first marked location on the screen. Savini exposed it with electronic flash at 1/5.6, using an 8fold star effect filter in front of the lens. The same CC10B filter as for the main exposure again served to correct the response of the film emulsion. To enhance the cool rendering of the star, Savini added a light blue 38 LB contrast filter. This procedure was repeated for every star.
The filter holders of the SINAR COLOR CONTROL filter system can easily accomodate three filters at a time. But a suitable hood must carefully screen the filters against any extraneous stray light.
For the ultimate image
Savini’s working sketches
Even a masterful style, with expert camera and lighting technique plus a near perfect filter system is not enough – methodical exposure metering and consistent procedure are equally important. Savini keeps a working sketch on which he meticulously marks every spot meter reading for each part exposure. He then adjusts the output of each flash generator and with an instant-print exposure checks each calculated effect on the whole exposure.
Daydreaming with the camera
The professional gets a real kick out of producing top-class pictures with sophisticated application of view camera techniques.
Initially, Savini only wanted a Polaroid instant picture to record the camera setup for his workbook – as he does with all exposures. But he got so fascinated with the illustrative documentation that it turned into a picture in its own right.
Savini fitted a 165 mm SuperAngulon lens on his second SINAR p – already set up to expose the stars – and with the swings defined a sharp plane from the front edge of the table at the left to the side of the camera at the left. He then directed a lamp at the black p2 and measured and adjusted the setup in his usual thorough way. For his self-imposed exercise Savini again used two separate exposures: The first for the subject and the camera, the second just for the ground glass screen image.
Needless to say, the photographer again relied on his expertise in filter control.
For if you look closely, there is the screen image in perfect colour, like the original shot – but what of the colours of the subject itself? And what happened to the table leg? Ask Savini. He will mount the polarising filter and a knowing smile .
But if you want to know more about the full SINAR COLOR CONTROL filter range and all the things you can do with it with view, rollfilm and miniature cameras, consult the SINAR COLOR CONTROL filter brochure.

Vladimir Bulović of electrical engineering and computer science (left), Miles Barr PhD ’12 (right), and Richard Lunt (below) are making transparent solar cells that could one day be deposited on everyday objects from mobile devices to windows, turning surfaces everywhere into low-cost energy-harvesting systems. This research was supported by the MIT Center for Excitonics, an Energy Frontier Research Center funded by the US Department of Energy. Photo: Justin Knight
MIT researchers are making transparent solar cells that could turn everyday products such as windows and electronic devices into power generators—without altering how they look or function today. How? Their new solar cells absorb only infrared and ultraviolet light. Visible light passes through the cells unimpeded, so our eyes don’t know they’re there. Using simple room-temperature methods, the researchers have deposited coatings of their solar cells on various materials and have used them to run electronic displays using ambient light. They estimate that using coated windows in a skyscraper could provide more than a quarter of the building’s energy needs without changing its look. They’re now beginning to integrate their solar cells into consumer products, including mobile device displays.


Inertial measurement unit (IMU) has long suffered from the problem of integration drift, where sensor noises accumulate quickly and cause fast-growing tracking errors. Existing methods for calibrating IMU tracking either require human in the loop, or need energy- consuming cameras, or suffer from coarse tracking granularity. We propose to augment indoor inertial tracking by reusing existing indoor luminaries to project a static light polarization pattern in the space. This pattern is imperceptible to human eyes and yet through a polarizer, it becomes detectable by a color sensor, and thus can serve as fine-grained optical landmarks that constrain and correct IMU’s integration drift and boost tracking accuracy. Exploiting the birefringence optical property of transparent tapes – a low- cost and easily-accessible material – we realize the polarization pattern by simply adding to existing light cover a thin polarizer film with transparent tape stripes glued atop. When fusing with IMU sensor signals, the light pattern enables robust, accurate and low-power motion tracking. Meanwhile, our approach entails low deployment overhead by reusing existing lighting infrastructure without needing an active modulation unit. We build a prototype of our light cover and the sensing unit using off-the-shelf components. Experiments show 4.3 cm median error for 2D tracking and 10 cm for 3D tracking, as well as its robustness in diverse settings.

It is widely believed that the current telecommunications network is required to grow by more than 10X in the coming years to satisfy the demands placed on it by an increasing number of connected devices, in particular content streaming to mobile devices. To enable this growth, significant enhancement in the bandwidth capacity of Photonics Integrated Circuits (PICs) is necessary. Contemporary high density PICs represent a significant thermal management challenge particularly for active optical components such as laser arrays. Each individual laser operates under tight, sub ambient temperature limits (0.1C) and extremely high heat fluxes (over 1kW / cm2). In addition, adjacent lasers require different operating temperatures, meaning local tuning of the thermal management solution. Thermoelectric modules (TEMs) and resistive heaters are currently used to achieve thermal control, however this method is limited by the packages environment and poor efficiency. In order to enable the next generations of PICs, Bell Labs Thermal Management Research Group in collaboration with the CTVR Telecommunications Research Centre has identified the need to move to a liquid based micro Fluidics cooling solution that can tackle the high heat fluxes while providing thermal control of individual optical devices within the photonics package. In this paper, the ongoing activities surrounding the integration of microfluidics within photonics packages are presented. This includes novel microscale pump and heat exchanger designs that are being developed to address key areas that currently limit the practical implementation of microfluidics cooling.

The 700F LED offers two independently growth areas making this model ideally suited for applications where smaller experiments need to be conducted in different environments, all in a small footprint. The standard lighting system of the 700F LED provides a broad based light spectrum for plant growth using a combination of Red, IR and Blue LED lights. LED lights allows a flexible choice of wavelength for larger panel of experiments. Morphology Analysis is done by capturing a series of images at intervals ranging from seconds to hours apart. Time lapse, areas measuring at different moment, the analysis software is a powerful tool who will convert the analysis in results.
LEDs present many advantages over alternative light sources including lower energy consumption, longer lifespan, smaller size, faster switching, less heat and greater durability/reliability. Typical LED lifespan is rated at 50,000 hours at which point light output has degraded only 30% from new.The output percentage of different light can be controlled simultaneously and the respective operating frequency and time can be set accordingly. The two compartments conditions can be set differently. 6 channels with frequency, duty ratio, intensity, phase shift ratio can be managed individually.
Humidity Range: 40% – 90%Uniformity: ±3% @ 80% RH
Low energy ultrasonic humidity generator available.Humidity affects plants in growth chamber directly by conditioning transpiration and other gas exchange and indirectly by modifying the plant’s energy balance and physical and biological environments. The most significant and direct influence of humidity on plants is on transpiration, the evaporation of water from plant surfaces into the atmosphere. Transpiration generally increases as humidity decreases.
Temperature range: 10°C ˜ 50°C
The 700F LED has a perfect temperature control thanks to its proportional system in which the rate of heating and cooling is propor tional to the deviation of temperature from the set point. The design of the 700F LED and its technology also allows to obtain a perfect temperature uniformity. The 700F LED is equiped with the last technology in term of LED growth chamber.

Plant Morphology Analyzer: Time-lapse photography thanks to the CCD camera allows to easily observe the development of the plant in interaction with the different elements. Time-lapse photography is done by capturing a series of images at intervals ranging from seconds to hours apart. When the images are viewed in rapid succession, much like a flip book, the effect is to compress into a short period, the changes that occurred over a relatively long period of time. Comparing the different succession of pictures allows the searcher to compare the effect of the variation of light, temperature, humidity and CO2 on the growth of the plant.
Contrary to the 700F LED where the camera is mounted on top of the instrument and images are taken from above, on the 700F LED the cameras are side mounted. This is the method of choice to monitor luminescence and fluorescence signals in leaves and shoot meristems.Yet, in many research projects it is necessary to monitor gene expression in roots and shoots and correlate to growth morphology. In order to not disturb the gravitropic behaviour the seedlings have to be maintained upright in their natural vertical orientation. The laterally mounted camera and the rotating table holding the trays with the seedlings in a vertical orientation are the solution. Videos from sequence measurements can be instantly created within a video software. Multiple or multiday measurements are managed through a scheduler, so that the software doesn’t need to be active all the time. Thanks to the powerful batch manipulation features e.g. small changes in the scaling can be applied to other images within seconds


Do you enjoy hunting or target shooting in your spare time? If either of these activities strikes a tone of familiarity with you, then not only are you comfortable with being outdoors, you’ve also probably entertained thoughts about outdoor optic devices.
After all, it’d almost be unthinkable trying to undertake either of these activities without a pair of binoculars. But in spite of their range, portability, and reasonable price tags, they’re hardly the end-all if steady-handed, long-distance viewing is what you’re after.
Telescopes, on the other hand, are incredible optic devices, but lack any semblance of the versatility, portability, and reasonable pricing that would justify bringing one along on a short- or medium-length excursion. There is, however, an option that’s positioned perfectly between binoculars and telescopes that’s compact and rugged enough to take hunting or camping, but still packs all the visual acuity of larger, typically stationary optical devices. And their price belies their performance. Yes, it’s scopes.
The focus on scopes
When crystal clarity at long distance is what you need, whether it’s tracking a boar at 500 yards at twilight, or reading targets downrange at 800 yards in broad daylight, you can count on a spotting scope to bring everything into focus.
These waterproof, shockproof, HD optic devices are easy to recognize from their angle-shaped bodies – but don’t let their less-than-comfortable looks fool you. They’re manufactured with straight bodies too, and yet it’s their classic, unconventional shape that provides the perfect ergonomic adaptation for how they’re most commonly deployed. For prone or low-lying positions (where the natural inclination is to hold one’s head down over long periods), and for viewing at upward angles as opposed to straight ahead.
Regardless of the body style though, there’s no change in the characteristic low-light performance, image sharpness, and wide field of viewing traits that scopes are known for. It’s their ability to instantly allow either extra coarse or superfine viewing adjustments that makes them ideal for any outdoor activity where high magnification, steadiness, and portability matter.
It’s these points, in fact, that relate most directly to the questions that need to be asked when an individual’s considering which type of spotting scope to buy:
- How much magnification do I need?
- How can I mount the device?
- How much of a factor is the device’s size?
Let’s take a moment and address each of these questions.
Magnifications of 20-60x or better is what you’d expect from a high-end scope. It means the scope will magnify an object between 20 and 60 times its actual size. A scope’s objective lens, i.e. the lens at the very front, determines the amount of light the scope is allowing in to power the magnification. Large objective lenses are what gives scopes their tremendous low-light viewing capability and they go hand in hand with superior magnification for making spotting scopes superior to any binocular, as well as most telescopes.
A stable support platform is mandatory to take full advantage of a scope’s superior magnification. Supporting one by hand will get tiring after a few minutes, outright undoable if you’re spotting game for hours, which is why a scope would typically be mounted on a tripod if the user is on foot, or on a window mount if spotting from a vehicle. Low-standing tripods are a particular preference of game hunters because it allows them to stay in their prone position, unexposed, and without any movement, reflections, or commotion that’s bound to alert prey.
Weight and mass matter when you’re on the trail, and although scopes don’t carry or stow away as conveniently as binoculars, they’re infinitely more portable than telescopes. A compact, angled 20-40x spotting scope for hunting with a 60mm objective lens is 239mm long and weighs only 400gr, while a robust 20-60x model with an 85mm objective lens is 400mm long and weighs almost 1730gr. The difference is noticeable, and the difference in performance is going to be even more noticeable. All factors regarding the scope’s size, including whether a tall or short tripod is preferable, have to be considered in conjunction with how you’ll transport them.
Going beyond hunting
Because of their excellent light transmission and field of view, scopes have been the optic device of choice for hunters and target shooters for a long time. The credit, however, really goes to their distortion-free, no-glare magnification. This makes them ideal for attracting an even broader segment of outdoor users who want durable, larger-lensed optics that can perform all kinds of tasks with the right accessories, but won’t cost an arm and a leg.
- With a camera attachment, a scope becomes a tool for outdoor photographers (called digiscoping).
- With a phone attachment, a scope becomes an instrument of discovery for bird and even offshore ship watchers.
- With a reticle attachment, a scope becomes a position finder for amateur astronomers or geodesists.
The final word
With all things considered, there’s no topping a spotting scope when it comes to getting the highest magnification possible in the toughest package possible.
From hunting and shooting, to ship and bird spotting scopes are an affordable, long-term way to make outdoor activities more interesting and appealing without substantial cost.
If you’re considering spending more time camping, hiking, or just enjoying the beauty of nature on a regular basis, a scope’s the ideal device to help you do it.

The interaction of light with matter offers an invaluable tool to characterize the properties of materials and, at the same time, can be exploited for applications in optical communications, data storage, or sensing.
In our lab the focus is on the tailoring of the spectral response of electromagnetic waves in complex materials, including strongly correlated electron systems, photonic crystals and plasmon resonators. Our recent investigations have demonstrated the possibility of having customized magneto-optic spectral responsiveness, with magneto-optic enhancements at particular light wavelengths when coupled to photonic or plasmonic structures. A particular attention is also paid to the effect on light polarization when it interacts with media that present ordered electronic states, such as magnetic or ferroelectric compounds, that is exploited to carry out submicron domain imaging.
Our lab has different equipment to carry optic and magneto-optic characterization:
Magneto-optic spectroscopy lab.
Magneto-optic spectroscopy form UV to near IR (wavelength range ~ 300 – 1200 nm). Measurements of Kerr/Faraday rotation and ellipticity and magnetic circular dichroism from 8 K up to 320 K, and with magnetic fields up to ~ 2 Tesla.
Confocal microscopy lab.
High-resolution imaging (below the micron) based on confocal microscopy with polarized light contrast. It allows obtaining mappings of rotation/ellipticity and circular dichroism, as well as linear dichroism effects. These possibilities are exploited to perform magnetic as well as ferroelectric domain imaging.
Optical reflectance spectrometer.
Reflectance spectra in the visible range as a function of the angle of incidence. It allows obtaining reflectance contour maps for wavelength range l » 400 – 800 nm and angle of incidence within (–40º, +40º). From these plots we can obtain the dispersion relationship w– k (frequency versus wavector) of light interacting with media (plasmon reonators, gratings, photonic crystals, etc.)
Magneto-optical set up with remote-control rotor stage. It allows the study of magnetic anisotropy with high accuracy in azimuth angle.

24 Jul Blue Light
what is Blue Light?
Visible light (or sunlight) is made up of different wavelengths of light – red, orange, yellow, green, blue, indigo and violet light. Blue rays are the shorter wavelengths and have more energy, whereas the red rays are longer and have less energy.
Blue light (a high energy visible light) is emitted from LCD and LED computer and television screens, smart phones, tablets and GPS devices. Blue light is natural and present in daylight – it helps us to stay awake. When your eyes are over exposed to Blue light it can cause eye strain, eye fatigue and sleeplessness.
How does Blue Light affect your eyes?
Most blue light passes through the cornea and reaches the retina at the back of your eye. Too much blue light can age your eyes prematurely and can cause Digital Eye Strain & Damage to the Retina.
Digital Eye Strain Symptoms:
– Tired, burning, itching eyes
– Light sensiivity
– Glare or halos around objects
– Fluctuating vision, worsening eyesight
– Blurred or double vision, difficulty focusing
– Dry eyes, excessive blinking
– Neck/shoulder/back pain or body fatigue
Retinal cells can get damaged over time leading to Macular Degeneration which can lead to permanent vision loss.
How can you protect your eyes from Blue light?
Hoya Hill Optics has created a lens that blocks out blue light when working on digital devices. BlueControl blocks blue light emitted from digital screens preventing eye strain and fatigue – your eyes feel more relaxed and your vision is improved! View more information here.
Hoya’s BlueControl lens uses Hi Vision LongLife (HVLL) technology:
HVLL is the hardest anti-reflection coating on the market today with a 3 year warranty on manufacturing defects!
Scratch resistant – You no longer need to worry about scratches with this scratch resistant layer.
Anti-reflective – The Anti-reflection coating allows light to pass through the lens improving the quality of vision and allowing your eyes to be more visible.
Water Repellent – Water drops just roll off your lens surface because of the minimal grip of the top layer.
Dirt Repellent – Dirt and grease wipe off easily because of the coating’s easy-to-clean properties.
Anti-static – An anti-static layer prevents dust adhering to the surface, ensuring clear vision. You also don’t have to clean your lenses as often.


Telescopes are optical instruments that focus light in such a way that distant object look magnified. Just one year after discovery of first modern telescopes, Galileo Galilei managed to create small telescope that had 30x magnification. If you feel adventurous, you can repeat that feat today!
Anyone who wants can create simplified version of telescope can do that using mostly home supplies – two magnifying glasses (2.5-3cm will be enough, also it is helpful if one is larger than another), cardboard tube, duct tube, scissors and a ruler. To determine the perfect distance between those two lenses, take the larger lens and put it away from yourself, and then place smaller lens between it and your eye. Move the lenses and position of your head back and forward until the image that you see through smaller lens is clear. At that time, ask for your friend to measure exact distance between two lenses. After that, take the tube and mark the positions where lenses need to slot in, insert them, and make sure they are not moving. After that you can use your simple telescope.
Another tactics is to take the tube and tape up smaller lens to one side of the tube. Then you need to look through smaller lens and tube beyond it, and take larger lens and manually position it in front of the tube. This process is little complicated, but it requires minimal effort for assembling the materials.
However, when we move from amateur telescopes and spyglasses to the more professional made one, things get little more complicated. Scientific telescopes demand much more advanced hardware and materials, starting from of course specialized lenses and mirrors that are optimized for telescopes. Main lens of the telescope has to be very pure, usually as pure as 99.9 % of silicon and just 0.1% of impurities. The glasses are separated into two groups – crown glasses (boron oxide, sodium oxide, potassium oxide, zinc oxide or barium oxide) and flint glasses (lead oxide). All glass components are made in furnaces that reach 1550 °C, which ensures that all air bubbles are ejected from it. To make glasses anti-reflective, they are coated with magnesium fluoride. Mirrors that are used are not as pure as glasses, but are made to be very accurate and coated with aluminum which provides best reflectivity.
One of the most important elements of the production of professional telescopes is quality control, which touches each step of the manufacture. Accuracy of lenses and mirrors is especially closely monitored, including their grinding, thickness, diameter, and curvature (which is measured with a device called spherometer). Tolerances for curved lens are usually plus or minus of 20 micrometers, while flat lenses (mirrors) are about plus or minus 1 micrometer (0.00004 inches).

An ADAS system uses a combination of top quality cameras and advanced processing technologies to detect potential safety hazards and react immediately. In most cars and SUVs, these cameras are installed on the inside of the windshield glass, the rear view glass or on the roof of the car.
In some cars, you will find two cameras mounted on the windshield. The ADAS system captures the images of the surroundings of the vehicle and supplies accurate data to the driver in real time. As soon as the driver receives crucial information in real time, he or she finds it easy to take action at the right time to avoid danger or the risk of serious injuries. These cameras have useful features to collect data and stream video for the driver to see in real time with low latency. This is exactly why the DAS system is one of the most important vehicle safety elements.
Not just the role, but you also need to understand the different camera features of a vehicle’s ADAS system. Knowing the features will help you select the right type of camera for the ADAS device in your car or SUV. Here are some of the key features that’s great ADAS camera has:
When it comes to ADAS cameras, you do not need to go for very high resolution. A camera with a resolution of 2 MP is suitable for the purpose. However, you can go a little beyond this resolution as well.
High Dynamic Range
One of the key features of ADAS cameras is HDR or High Dynamic Range. The ADAS systems are designed to perform in a range of lighting conditions, from bright areas to dark areas. Therefore, HDR cameras are ideal for ADAS devices, as they prevent overexposure and underexposure.
For the ADAS system to function properly, the camera interface should be able to transmit data for over a distance of 10 meters with a high level of accuracy. Equipped with such an interface, the distance between the camera and the host processor does not create any problem. That is exactly why you should opt for GMSL cameras for the system to function efficiently.
LED Flicker Mitigation
Most vehicles come with LED light, which makes it difficult to read the images. In order to eliminate the problem of flickering for easy reading, you should install a camera with LFM feature. These cameras are designed to accurately capture images even when the LED lights are very strong.
The cameras you choose should also have low latency. This feature will help the quick and easy transfer of captured images to the display in real time. The feature enables the system to take automated decisions.
The compatibility of the ADAS camera with the processor is important. If there is any kind of incompatibility between the two, the system will fail to deliver high-precision results. There are many ADAS cameras that are pre-integrated with certain types of processors. Make sure you consider the platform compatibility or get those cameras that are already integrated.
Hopefully, you have understood the key features of ADAS cameras. If you still have a question or seek expert help in the selection and integration of cameras into your ADAS device, do not hesitate to reach out to one of our specialists at SIR Auto Glass in the Portland metro area, OR.
