The Story behind the Invention of the Space Telescope
The Space Telescope is a pioneering invention that led to a plethora of profound discoveries about the infinite mysteries of galaxies, stars & planets. A telescope is an instrument to view distant galaxies, black holes, celestial bodies & astronomical objects. The invention of the space telescope was a major step in the evolution of the dynamics of space science.
The first operational telescopes were the American Orbiting Astronomical Observatory, OAO-2 launched in 1968, and the Soviet Orion 1 ultraviolet telescope aboard space station Salyut 1 in 1971.
The Science behind a Telescope
A telescope has two principle properties:
- The ability to collect light
- The ability to magnify an image
A telescope's ability to collect light is directly proportional to the diameter of its lens or mirror known as the aperture -- that is used to gather light. In general, a larger aperture has the ability to collect and focus more light. It also makes the final image brighter.
A telescope's magnification is its ability to enlarge any image depending on the combination of the lens used. The eyepiece is used to perform the magnification. Magnification can be achieved by almost any telescope using different eyepieces while the aperture is a more dominant feature.
Brilliant Minds behind the Invention of the Space Telescope
Galileo was widely accepted as the first inventor to point a telescope towards the sky where it could reach magnifications of around eight to twenty times. His telescope was able to view mountains and craters on the moon, as well as a ribbon of diffused light arching across the sky which is famously called as the Milky Way. Galileo is also famous for discovering the rings on Saturn, and Jupiter's moons.
The telescope has undergone significant transformations since its first patent registered in the 17th Century. Some of the greatest minds from Galileo Galilei to Sir Isaac Newton to the great Edwin Hubble would all eventually contribute to the development of this advanced scientific piece of equipment. Many historians recognise Hans Lippershey as the inventor of the first telescope, as he was the first to apply for a patent. After the ground-breaking work of Hans Lippershey and Galileo Galilei, other scientists around Europe began to design and build their own telescopes.
Impact of Space Telescope on Astronomy & Science
Telescopes have given us significant insights into the workings of the universe, allowing science to progress. With the use of the telescope, we realised that the sun was truly at the centre of our Solar System. If it wasn’t for the invention of the telescope, we would not have been able to observe stars & planets that are millions of miles away from us. Telescopes have also allowed us to see the surface of the moon and the weather patterns of other planets.
Evolution of the Space Telescope
The Telescope has contributed to a vast array of discoveries that paved the way for astronomy to exfoliate the mysteries of our universe to a high extent. Modern telescopes now can detect heat and radio waves. Telescopes demonstrate how our planet interacts with others, and they can illustrate the properties of physics such as gravity, energy, etc.
More recently, telescopes have allowed us to examine galaxies having planetary systems similar to our very own! We may be able to pinpoint planets where conditions can sustain life like the Earth.
Modern Space Telescopes
- The Hubble Space Telescope is perhaps the most well-known of the modern-day telescopes. The space telescope is 13.2 meters long and has a 4.2-meter diameter. It launched in 1990 and has completed more than 1.3 million observations since then.
- NASA is just recently launched James Webb Space Telescope. The Webb telescope primarily acts as an infrared telescope. The mirror in the Webb Telescope comprises 18 different segments that adjust and fold.
The invention of the Space Telescope played an instrumental role in perpetuating our understanding of Earth's place in the cosmos. Besides raising the horizons of ingenuity, the invention of the telescope has also played an evocative role in increasing the intrigue of astronomers and astrophysicists around the world. So, if you have a passion for space science and wish to learn more about the universe, then get a telescope and hone your physics and mathematical skills!


Simple LDR Circuit
Here is very simple circuit for activating a light in darkness using LDR and few components. Here LDR is used as sensor and Transistor is used as electronic switch.
Project Model based on LDR
Simple LDR Circuit Diagram
When light falls on the surface of LDR, the LDR changes its resistance. The more the light, the less the resistance. Resistance R1 (100K) and LDR is connected in series and makes a potential divider circuit. Divided voltage varies according to the intensity of the light. LDR is connected with Ground so voltage drop increases when light intensity increases. It responds to large part of light spectrum.
The centre point of the Potential Divider is fed to a NPN Transistor BC147/BC548. This general purpose NPN silicon transistor conducts when base voltage is approx 0.5V or above when compared to emitter voltage and circuit gets completed thus LED glows in darkness.
b) 100K Resistance
c) Transistor BC548
This Magic Eye circuit is very cheap and easy to make. Will cost you arround 20 Cents (Rs 15) only.

The ND filters are specifically designed for the Pavo Pico Brushless Whoop Quadcopter. Meanwhile, the DJI O3 Air Unit ND Filters are tailored for the DJI O3 Air Unit and are capable of reducing the amount of light that enters the camera lens. With this feature, you can achieve slower shutter speeds or wider apertures when flying. These lightweight filters are crafted from high-quality optical class ensuring optimal image clarity and are too easy to install on the build.
- DJI O3 filters are easy to install and protect your camera lens from dust, sand, and debris. They ensure uninterrupted high-quality footage during flights and extend the life of your equipment. Customized filters for your drone can enhance your footage and equipment protection.
- ND filters reduce sunlight brightness, lower camera shutter speed to avoid overexposure, prevent distortion in high-speed motion blur shots and improve drone footage quality.
- UV filters effectively minimize the blue tone caused by ultraviolet rays in outdoor photography, resulting in clearer, more saturated, and more realistic images. They also protect the camera lens from dirt, sand, and scratches.
- CPL filters reduce light and mirror reflection, preventing overexposure and white reflections. They improve clarity and brightness, especially over water or reflective surfaces, resulting in a more detailed image with reduced glare.
The filter supports two installation methods, To install the filter, align it with the lens position and clip it into the frame horizontally or vertically. To remove it, grip the lens mount with your thumb and pull it out.
Horizontal installation of the UV filter is more suitable for shooting ground or scenery as it effectively reduces reflections and scattering, avoiding excessive refraction of light that may affect image quality. It also provides added protection to the camera lens surface, reducing the risk of damage. Vertical installation of the UV filter is best for shooting reflective surfaces such as water or glass, as it better reduces reflections and prevents them from interfering with the shot.

Fiber optic camera allows you to see from another room, from under a door, and through walls. This is especially designed for inspection work. It features a flexible optic bundle with built-in eye piece at one end, and a 2-3mm diameter lens on the other. It’s easy to use. Just put its header under a door to see what is happening on the other side.
Features of a fiber optic camera
Maintenance of image quality and control data integrity over far distances
This is the major feature of staple optics; they have superior signal frequency attributes compared to copper cable. They generate co-axial cable attenuation at a signal frequency of 3-5 MHz and can also be converted to 20 dB/km. In comparison to other transmitters, fiber optics attenuation is between 0.3 and 3 dB/km. This means fiber or staple optic transceiver can cover up to 60 km or more, depending on the precise details of application. Since these transceivers 25g sfp28 feature a conversion of low fiber signals, it can also function as a transmission of multiple video signals over long distances.
Information Security and Safety Operations
Unlike traditional copper cables, fiber optics does not radiate any signals. As a result, these optical cables are virtually immune from wiretapping. The signal frequency is difficult to access for unauthorized parties. There is no risk for installation of fiber or staple optic. It can act as the ignition source for all multiple signals. It can also be used in hazardous environments such as chemical and petro-chemical sites, providing an “intrinsically safe” transmission route; however, this safety may not extend to the electro-optic transmission routers and modems. It may not be guaranteed safe and protected compared to other electrical equipment.
Accurate use of duct space
Fiber optic transceiver features small and durable lenses. It has protective sheathing applied in different phases, depending on the installation area, to build up the fiber into a multipurpose cable. This cable is suitable for both internal and external use. Generally, its coaxial cables can produce significant savings over copper where there is not enough installation space or where duct space is often restricted.
Resistance to electromagnetic interference
Fiber optic transceiver transmits signals as light pulses instead of electrical pulses. This light transmission process is not affected by the electro-magnetic materials. As a result, the transmissions can be utilized in other application where links are routed near energy conductors and other machines including tramways, power generator, railways, and automobile manufactured with welding machinery.
The fiber optic cable also features metal-free construction. This prevents loop problems between non-transmitting light pulses and terminal equipment. The prevention of ground loop enables the media of choice for building links of every distance.


Laser safety is a crucial aspect of any event, especially in the UK where the use of lasers is heavily regulated. Lasers are often used as a special effect at music events, concerts and festivals – but may also be used at corporate events or at religious ceremonies.
Event Safety Plan specialist Sam White looks at some tips for ensuring laser safety at events:
Comply with regulations:
In the UK, the use of lasers is regulated by the Health and Safety Executive (HSE) and the Control of Artificial Optical Radiation at Work Regulations (AOR). It is important to comply with these regulations, which include guidelines for laser classification, laser safety officer (LSO) appointment, and risk assessments.
Appoint a Laser Safety Officer (LSO)
The LSO is responsible for ensuring that the laser equipment is used safely and that all necessary precautions are taken to protect the health and safety of those present at the event. The LSO should have a good understanding of the hazards associated with the use of lasers, and should be trained in the appropriate use of laser equipment.
Conduct a Risk Assessment
A risk assessment should be conducted to identify any potential hazards associated with the use of lasers at the event. This should include an assessment of the audience, the laser equipment and the event environment. The results of the risk assessment should be used to develop a laser safety plan for the event.
Use appropriate laser equipment
It is important to use laser equipment that is appropriate for the event, and to ensure that the equipment is in good working order. This includes ensuring that the laser equipment is properly labelled, has been provided by a competent contractor and that it is being operated by trained personnel.
Have an emergency plan in place
Having an emergency plan in place is essential in case of an incident involving laser equipment. The emergency plan should include procedures for responding to an incident and for providing medical attention if necessary.
By following these tips, you can help ensure that safety is a priority, and that all necessary precautions are taken to protect those working at or in attendance. Remember to stay informed and up-to-date on the latest laser safety guidelines and regulations, and to work closely with the Laser Safety Officer (LSO) to ensure that the laser equipment is used safely.


Pocket Mirror For Men – While driving, the traffic situation on the road keeps on changing within seconds since it’s a dynamic process. Drivers maintain their focus on amassing awareness about traffic ahead, ignoring the traffic situation on sides and rear of the car. They don’t use rear view and side mirrors (fender or wing mirrors) for properly observing the space between you and side driver. Vehicles lacking special purpose side mirrors cause severe accidents and even traffic jams. Negative mirrors, also called wing mirrors, are mainly positioned at the exterior of the cars helping the driver to eye on the areas supporting and surfaces of the car that doesn’t encounter his peripheral vision. Horizontal and vertical adjustments of those mirrors are designed to provide adequate coverage to the drivers of varying height.
In most cars, mirror glasses are electrically heated and occasionally include electro chromic dimming that helps in reducing glare from the head lights of the subsequent vehicles. Some of them are armed with turning signals, which not only give safety throughout the driveway but also an appealing appearance to the vehicle. Experts think that side-view mirrors prove beneficial for the drivers to see people driving in their own lane and at the rear. Some fender mirrors may be brushed or manually shielding them from any harm when the car is parked. Automobiles passing your automobile can easily snip protruding wing mirrors. Hence, the folding capability protects them from any harm.
Earlier flat mirrors were utilized with unit magnification, i.e. that an undistorted 1:1 image was obtained, but unit magnification restricts the area of vision. Later, UNECE (United Nations Economic Commission for Europe) controlled to use convex, planar, or aspheric mirrors. There’s a considerable distance between the driver’s eye and passenger side mirror; therefore, a very helpful field of view can only be attained using an aspheric or convex mirror. Convex mirrors decrease the objects. This makes these objects appear farther than their first space. It might give the wrong idea to the driver about space of the subsequent car, and he will change the lane imagining safe space between them both.
Adjusting Side-View Mirrors
Proper positioning of those mirrors is crucial for good visual habits as the purpose of mirrors is to detect, to not gather information. Adjustment of side-view mirrors is very straightforward.
1. To correct the driver’s side-view mirror, put your head next to the left side window and then bend the mirror so that you can just see the side area of your vehicle.
2. To correct the passenger’s side-view mirror, put your head in such a way that it’s just over the middle console. Now, set the mirror so that you can barely see side surface of the automobile at the left portion of a mirror.
Since the high heeled morning begins, auto protection becomes a critical issue. Be certain that your car is equipped with crucial driving accessories such as side-view mirrors.

Mirrors are everywhere in our daily lives. Existing computer vision systems do not consider mirrors, and hence may get confused by the reflected content inside a mirror, resulting in a severe performance degradation. However, separating the real content outside a mirror from the reflected content inside it is non-trivial. The key challenge lies in that mirrors typically reflect contents similar to their surroundings, making it very difficult to differentiate the two. In this paper, we present a novel method to accurately segment mirrors from an input image. To the best of our knowledge, this is the first work to address the mirror segmentation problem with a computational approach. We make the following contributions. First, we construct a large-scale mirror dataset that contains mirror images with the corresponding manually annotated masks. This dataset covers a variety of daily life scenes, and will be made publicly available for future research. Second, we propose a novel network, called MirrorNet, for mirror segmentation, by modeling both semantical and low-level color/texture discontinuities between the contents inside and outside of the mirrors. Third, we conduct extensive experiments to evaluate the proposed method, and show that it outperforms the carefully chosen baselines from the state-of-the-art detection and segmentation methods.

BEATRICE-CARMEN ZELINSCHI, CARMEN-FELICIA DASCALU, DANA ORTANSA DOROHOI INTERFERENTIAL WOOD FILTERS WITH CHEMICAL PURE QUARTZ FROM MARAMURES AREA AS ANISOTROPIC LAYER
Preliminary XRD and optical studies regarding the purity and the transparence of some quartz samples provided from different Romanian mountains areas, conducted us to choose the quartz crystal from Maramures area in the design of some Wood interferential optical filters working in the visible range. The interferential Wood filter consists from an anisotropic layer between two crossed polarizers. For the selected quartz crystal, the birefringence dispersion can be neglected. Consequently, the value of the birefringence measured at l =589.3nm was used in the simulation process. A decrease in the band-width of the transmission bands was evidenced when the thickness of the anisotropic layer increased.

Samsung trying to outrun rivals in the camera game.
Samsung has now unveiled the first 200MP camera sensor for smartphones, ISOCELL HP1. It is based on Samsung’s 0.64μm sized pixels. It provides ultra-high resolutions in the small packaging, ice on the cake.
New Samsung ISOCELL HP1 provides amazing low light performance because of ChameleonCell pixel-binning technology. ChameleonCell pixel-binning technology allows the sensor to use two-by-two, four-by-four, or full pixel layout according to the environment. In low-light conditions, the new Samsung ISOCELL HP1 can merge 16 neighboring pixels into a large 2.56μm sized pixel. A larger size pixel helps to capture more light and results in brighter photos.
“ISOCELL HP1 can also produce
the 8k video at 30fps.”
ISOCELL HP1 can also produce the 8k video at 30fps and minimum loss in view. The new sensor merges the four neighboring pixels to create a 50MP effective resolution and results in 8k video with no need for cropping or scaling down image resolution.
Along with the stunning ISOCELL HP1, Samsung also announced the ISOCELL GN5. ISOCELL GN5 is the industry’s first 1.0μm to integrate dual-pixel pro. Duel-pixel pro is multi-directional autofocus technology.
“Places two photodiodes, the smallest in the industry, within each 1.0μm pixel of the sensor either horizontally or vertically to recognize pattern changes in all directions. With one million phase-detecting multi-directional photodiodes covering all areas of the sensor, the ISOCELL GN5’s auto-focusing becomes instantaneous, enabling sharper images in either bright or low-lit environments.”
-Samsung on ISOCELL GN5
ISOCELL GN5 uses Samsung’s very own pixel technology that applies Front Deep Trench Isolation (FDTI) on a Dual Pixel product for the first time in the industry. This technology allows each pixel to hold more information about light and improves its full-well capacity (FWC) along with decreasing crosstalk within the pixel.
Samsung has shared no information about when will see the new sensors in Samsung smartphones. Samsung might equip these in the company’s new Flagship S22 series, but we are not sure. Stay tuned, we will let you know.


What is PDLC smart film glass?
PDLC (Polymer Dispersed Liquid Crystal) Glass is a kindly laminated glass, which can change to be transparent or opaque instant by switching the electricity power by means applying with PDLC film. When power off, coming visible light scatters through the PDLC, and the film turns translucent;When power on, coming visible light transmits the PDLC and the Film turns clear.
1.Privacy protection. As most important function, smart glass can be changed from transparent to opaque via easy model ON & OFF.
2. Perfect function of safety. As smart glass is a special kind of laminated glass, it has all the good function of the laminated glass, mainly the security.
3. Blocks more than 99% UV rays ,avoiding fading in the room.
4. Sound proof. With excellent damping action, the smart glass is easy to block the noise.
5.Projection. When it is under suitable light, the perfect projection appears.
6.No trouble of curtain setting and cleaning.
7.With a modern looking, very good for interior design.


Second Sight Medical Products, Inc., located in Los Angeles, CA, was founded in 1998 by Alfred Mann to develop a retinal prosthesis to provide sight to patients blinded from outer retinal degenerations, such as Retinitis Pigmentosa.
Second Sight’s Argus II Retinal Prosthesis System is intended to provide electrical stimulation of the retina to induce visual perception in blind individuals. The implant is an epiretinal prosthesis surgically implanted in and on the eye that includes an antenna, an electronics case, and an electrode array. The external equipment includes glasses, a video processing unit (VPU) and a cable.
The Argus II Retinal Prosthesis System bypasses the damaged photoreceptors altogether. A miniature video camera housed in the patient’s glasses captures a scene. The video is sent to a small patient-worn computer (i.e., the video processing unit – VPU) where it is processed and transformed into instructions that are sent back to the glasses via a cable. These instructions are transmitted wirelessly to an antenna in the implant. The signals are then sent to the electrode array as pulses which bypass the damaged photoreceptors and stimulate the retina’s remaining cells, which transmit the visual information along the optic nerve to the brain, creating the perception of patterns of light. Patients learn to interpret these visual patterns.
In Mach 2, 2011, Second Sight announced that it had received the CE Mark for the Argus II retinal prosthesis.

Criteria for Evaluating The Best Hunting Binoculars
When it comes to the magnification, bigger isn’t always better, and you need to know the range at which you intend to hunt to get the best binoculars for hunting deer.
If the magnification is not high enough, you’ll end up not seeing the elk you’re hunting properly and in time. However, if it’s too high you might have a pair of hunting binoculars that require a tripod to steady and have a narrow FOV.
For hunting in the woods or hunting faster deer, you will need binoculars with smaller magnification, 6x to 8x would be ideal. You will be able to have a wide field of view to track your pray easily, and trees won’t block your view too much.
Hunting in the plains, the mountains, the desert or other open spaces that need you to observe from long distances requires larger magnification. 10x magnification or preferably more is a good choice here. This will allow you to spot the deer long before it can spot you.
If you’re unsure about which magnification you need, pick one between 7x and 10x since that will fit most hunters. Don’t pick binoculars with too many superfluous since most of them lack certain essential features like waterproofing and can be too heavy. 10 x magnifications is not a significant upgrade over 7x though lots of hunters are under the impression that it is.
Frequently Asked Questions (FAQs):
What are the best binoculars for deer hunting?
Apart from varmints deer are the most popular quarry for American hunters, so that’s probably the biggest market for hunting binoculars. All the same, factors apply here, but there are a few things about deer hunting to take into consideration.
Deer are woodland animals, so you’re usually going to be bow hunting or rifle hunting in and around cover. That makes magnification less critical because the ranges you’ll be working at aren’t that great, so a steadier image is likely to be at a slightly more magnified one.
What are the Best Hunting Binoculars for the Money?
While this answer is somewhat subjective, the Bushnell Legend Ultra HD gets great reviews, and is a reasonable price point for binoculars made by a manufacturer with a track record in hunting optics.
What are the best value compact hunting binoculars?
The Bushnell Powerview is an excellent choice if you are looking for both cost-effectiveness and value. They come in many different magnifications while remaining compact, and are extremely budget-friendly.
What are the best hunting binoculars for buck hunting, elk hunting or for other big games?
The Bushnell Green Roof Trophy Binoculars are a great 10x magnification option, especially for hunters on a budget.
What are the best hunting binoculars on a budget?
Another vote for the Bushnell Green Roof Trophy binoculars due to cost. 10x magnification power with a strong performance track record and fully multicoated optics are hard to beat.
I hope I’ve managed to help you choose the best hunting binoculars and that my reviews of the best binocular brands on the market. These binoculars are most certainly worth the price, and they’re just the best ones all-around.
Finding the right pair of binoculars is no different than choosing the right pocket knife or fixed blade survival knife for your outdoor excursions. You need to understand what it is that will best fit your needs and pick the model that you will get the most use from.
While we can provide you with all the guidance in the world, only you can narrow down the Binoculars that are best for your unique hunting situation. Our parting thoughts are that if you are spending most of your time hunting in the daylight and not at dawn or dusk, go with the 10×42 magnification and spend a little more than you had originally planned on.
The quality will be worth the investment. If you intend on hunting at a wide variety of times and need something that’s easier on the wallet, the 8×42 options are great.
Compact Binoculars should only be purchased if you are needing something very portable or are tight on cash. These will work in a pinch but not as good as the other models that were made for a better field of view.

This thesis investigates the use of the large-area, roll-to-roll compatible deposition technique of ultrasonic spray coating for the fabrication of polymeric organic light-emitting diodes (OLEDs). Firstly, in Chapter 4 a range of different materials are investigated as potential solution processable electron-injection layers, typically this layer is deposited via thermal evaporation in OLEDs.
A range of new materials for organic light emitting diodes (OLEDs) synthesised in the Department of Chemistry at Durham University have been characterised and electroluminescent devices containing these materials have been optimised. High triplet oxadiazole based electron transport materials were tested in devices blended with the host material poly(9-vinylcarbazole) (PVK).

The main body of work examines various organic semiconductor materials in their ability to reach the strong light and matter interaction regime and, subsequently, to be used in OLEDs as the emissive component. Furthermore.Organic light emitting diodes (OLEDs) are being commercialized in display applications, and will be potentially in lighting applications in the near future. This thesis is about the design of high performance OLEDs, which includes both the electrical and optical design of OLEDs. In particular, the following work is included in this thesis: i) Energy level alignment and charge injection at.
Indeed, most applications of organic light-emitting diodes are related to visible light emission (e.g. illumination, signs and displays). That is the reason why the optical characteristics of OLEDs are usually given and compared in photometric units (not radiometric). Photometry is essentially radiometry normalised to the spectral response of.

Night Sights for Lever Action Rifles? You Bet!
Rapid target acquisition with bright, clear sight picture (day or night); Secondary “holdover” aim point for "on the fly" shooting at greater distances; Flush mounted rear sight on a precision machined scope mount rail.
Prior to this first-of-its-kind integrated backup sights system, virtually all gun sights designed for use as a backup to primary optical scope systems, particularly on traditional, dropped comb rifles, forces the shooter to mount the primary optical device in a high or otherwise unwieldy position. Additionally, most sight systems have been a compromise between large, open apertures, which afford good light throughput at the cost of precision, or smaller “peep” apertures, which afford better precision at the cost of poor light throughput. Lastly, non-glass aiming devices - commonly referred to as iron sights - have only afforded one aiming point, with no provision for secondary aiming points "on the fly" for shooting at greater distances. HIGHLIGHTS: - Rapid target acquisition and a bright, clear sight picture via a hybrid rear sight design, which combines a wide oval shaped aperture with an open top for good light throughput - Night sights use glow in the dark paint that can be illuminated with a flashlight and stay glowing for 1-3 hours - A precise aiming point, by utilizing rear sight “reticle” bars that align with a triangular front sight - A means of quickly estimating secondary “holdover points” by incorporating elevation notches in the front sight triangle - Elevation and windage adjustable without punches and hammers AVAILABILITY: - Marlin 336, 1894, 444 and 1895 rifles today! - Henry 30-30, 45-70 (June 2016) - Universal Sight Sets for most make/models of rifles - front/rear sight dovetail attach, no scope mount needed (end of June 2016)
