Many nanoparticle analysis techniques focus on size at the expense of shape. Advanced particle size measurements, such as dynamic light scattering (DLS), often assume a uniformity of shape to statistically generate performance predictions based on the hydrodynamic diameters of particles in solution. This is suitable for many applications. However, manufacturers are increasingly becoming aware of the limitations of such techniques. Particle shape analysis has become more and more prevalent within the industry for more accurate predictions of raw material performance in processing, packaging, transit, or end-use conditions.
Outlining Dynamic Imaging Particle Analysis (DIPA)
Image analysis is the ideal solution for particle shape analysis. In terms of classical measurement techniques, imaging particle analysis is closer to conventional microscopy than the likes of DLS. Just like optical microscopy, dynamic image analysis relies on visible light to illuminate samples and resolve the minute geometric differences between discrete particles and agglomerated structures. The primary difference between microscopy and dynamic imaging is the use of high-speed digital cameras that can capture live imagery of thousands of particles, significantly improving workflows and eliminating the risk of inaccuracies due to in situ human error.
Dynamic imaging particle shape analysis subsequently uses statistical measurements based on tens of different shape parameters. These include – but are by no means limited to:
- Circularity, rectangularity, ellipticity, convexity, and surface uniformity
- Compactness and smoothness
- Equivalent circular area / perimeter diameter
- Bounding rectangle length / aspect ratio
- Fiber length / curl
- Polygon order
This list is just a small sample of parameters that dynamic imaging particle shape analyzers may consider as part of an overall analytical run. Some of these factors are closely interrelated. Circularity can be construed as a measure of perimeter smoothness against particle form, for example. These interconnecting properties are part of the reason why many dynamic image particle shape analyzers use histogram overlays for image comparisons, and why some measurements are usually run before others. Area (number of pixels) is the simplest, and therefore the first, measurement usually conducted but the data acquired may then inform further statistical analysis (i.e. circular equivalent diameter).
There is a complex interplay between distinct particle shape parameters, and it is important to accurately characterize raw materials using as many data points as possible to provide quantitative insights for accurate quality and process control.

Leica Monochrom - or the invention of a pocket-size field camera
for extraordinary photographs
my CAMERA of CHOISE
For each of my projects I spent many hours or even several days. After some experimentation phase with different camera types and systems I came to the conclusion that the Leica Monochrom fits for me best and that it has much to offer in architectural photography.
Beside the famous Leica lenses high optical quality one of the big advantages of the Leica M system is it’s handy format for me.
ONE OF MY FAVORITE LENSES
The Leica Elmar-M 24 mm f/3.8 is my lens of choice for architectural photography. This lens has an extraordinary sharpness and an astonishing depth of field with almost no distortion. I think working with a 24 mm lens creates a very natural perspective that serves in architectural photography very well.
unsurpassed Picture quality
Architectural photography is typically created from different angles and views of a building. What's really compelling about the Leica Monochrom is the clarity and quality of its raw pictures itself. The Monochrom renders shadows and light in a spectacular way and gives each photograph its own unique visual quality.


Luminous intensity is the ability to emit light into a given direction, or it is the luminous flux that is radiated by the light source in a given direction within the unit of the spatial angle. If the point light source emits Ø lumens into a small spatial angle ß, the luminous intensity is I=Ø/ß.
The unit of luminous intensity is candela. There is a standard that details the candela definition. This includes the standard light source and the physical conditions of the measurement.
This definition determines the amount of light that covers a surface. If Ø is the luminous flux and S is the area of the given surface, then the illuminance E is determined by E=Ø/S.
The unit of illumination in SI system is lx, and in foot-pound system it is foot-candle. One lx is the illuminance of 1 m² surface area uniformly lighted by 1 lm of luminous flux. The following drawing explains this definition. One foot-candle is 10.76 lux.
Luminance L is the luminous intensity emitted by the surface area of 1 cm² (or 1 m²) of the light source. Mathematically it is L=I/S where I is the luminous intensity and S is the area of the source surface perpendicular to the given direction.
The unit of luminance is cd/m² or cd/cm² (in some applications lm/cm² or Lambert can be used). The following figure shows the concept.
The luminance value indicates glare and discomfort when we look at the lighting source. These values are very high for the sun or a small lamp and are low for large lighting fixtures.

Fluorescence correlation spectroscopy is a technique which provides correlation analysis of the fluctuations of fluorescent intensities from single fluorescent molecules. The spatial and temporal analysis obtained is high resolution and can describe mobility coefficients, local concentrations and characteristic rate constants of intermolecular reactions for fluorescent molecules.
FCS is performed on a Leica SP5 SMD gSTED microscope (see specification) equiped with single photon avalanche detectors (SPADs) and integrated Symphotime analysis software.
Fluorescence after Photobleaching (FRAP)
Fluorescence recovery after photobleaching (FRAP) relies on the photobleaching effect; a fluorescent molecule will be rendered unable to fluoresce after illumination with high intensity high energy light. By bleaching a small region containing fluorescent molecules it is possilbe to visualise, typically in the lateral plane, the movement of fluorescently active molecules across this 'dark' region. FRAP is commonly used for the investigation of lateral diffusion of molecules across the plasma membrane.
Within ESRIC FRAP is performed on an epifluorescent Olympus IX81 fully motorised microscope (see specification), controlled by Olympus Cell Xcellence software, using TIRFM and an integrated FRAP device.
Single particle tracking-photoactivatable localisation microscope (spt-PALM) describes the application o
f PALM to live cells, using photoactivatable fluorophores, typically at the plasma membrane. The high degree of noise detected when imaging single molecules at fast frame rates means de-noising algorithms are required, which can identify each molecule and deliver quantitative data describing each molecule's trajectory. The image on the right shows published data of single SNARE molecules tracked inside a living neuron and the trajectories of those molecules quantified.
spt-PALM is currently available on the epifluorescent Olympus IX81 fully motorised microscope (see specification) controlled by Olympus Cell Xcellence software under TIRFM.


Getting an acceptable image on a DSLR is generally not difficult. Getting a professional, consistent, stable image is occasionally very hard.
The single greatest aspect of achieving a pleasing image is ensuring the image is exposed well. Exposure is the process in which light reaching the camera’s sensor is absorbed, quantified, converted to an electrical signal and digitally coded into a recorded image. It is comparable to the photochemical film equivalent of light reaching the photosensitive film in sufficient quantity, so it can be developed later. Continue reading “Video production – Exposure”

I decided to actually sort out what about my camera made focusing my f/1.4 manual lens so hard and I found this article about fast manual lenses and modern DSLR cameras. The root of the problem is how the camera splits light between the view finder and the auto focus sensors. The long and short of it is, that no matter how big your aperture, what you see in the view finder will likely be f/4 or smaller equivalent (at least with a entry or mid level DSLR).
This matches my experience. The depth of field in the view finder is huge even when the aperture is wide open (and you can verify that it is open by looking in the front of the lens). Even more frustrating is the fact that live view very obviously shows the correct depth of field.
This makes finding sharp focus through the view finder impossible, or at least very improbable and unrepeatable if you are using a very fast manual focus lens. The solution: use main sensor based live view and on screen zoom (when possible) to achieve razor focus.


MD) OLYMPUS C-3040 ZOOM DIGITAL
An upgrade to Olympus’s respected C-3030, the C-3040 adds a faster f1.8 lens and better USB connectivity to the extensive features it shares with its predecessor. The new f1.8-2.6 lens is clearly the central feature of the new model. According to Olympus, the lens lets the C-3040 shoot in lower light conditions, which allows you to shoot flash-free in more situations and increases the effective range of the flash. The 3.34 megapixel CCD in the C-3040 captures images at a resolution of 2048 x 1536, in both the JPEG and uncompressed TIFF formats, and a 32 MB internal buffer allows you to shoot at 3.3 frames per second at high resolution and low compression levels. Additionally, the camera can record short QuickTime movies with sound.
The camera can be operated in several modes: in programmed auto mode, the camera does everything for you; in aperture and shutter priority modes, you get to set the aperture or priority, and the camera does the rest; in full manual mode, you have control over all camera functions. Images can be downloaded to either a Mac or PC via the included USB cable, or viewed on your television using the included video cable. The camera includes USB storage class connectivity, which means it can be connected to any USB-based Windows Me/2000 and Mac OS 8.6 or later computer without installing any software. The C-3040 also ships with two CR-3V batteries (four AA batteries can also be used), a 16 MB SmartMedia card, strap, remote control, and software.

The hidden ability of synchrotron radiation to perform coherent control
Researchers have discovered that synchrotron radiation from relativistic electrons has a hitherto unremarked ability to manipulate populations and pathways in matters. There is no technical restriction on the application of this brand-new coherent-control concept at shorter wavelengths as far as the hard x-ray range.
Coherent control is a method to manipulate the populations and pathways in matters by light and is currently one of the most attractive research areas in optical physics and photochemistry. Lasers have been considered as unique light source enabling one to perform coherent control, and, thanks to the development of laser technology, the on-going research is moving rapidly into the regime of extreme ultraviolet wavelength.
Synchrotron radiation from relativistic electrons is widely-used light with a continuous spectrum extending as far as the hard X-ray range. Synchrotron radiation is usually considered as being of poor temporal coherence, therefore nobody thought that it has a hidden capability of coherent control. Yasumasa Hikosaka (University of Toyama), Tatsuo Kaneyasu (SAGA Light source / Institute for Molecular Science (IMS) ), Masahiro Katoh (Hiroshima University / IMS) and co-workers have demonstrated this capability by achieving wave-packet interferometry on electron wave packets generated in Helium atoms.
The researchers employed two identical undulators installed into a straight section of the UVSOR-III storage ring at Okazaki, Japan. The twin undulators generated a pair of linearly-polarized electromagnetic wave packets, where each of the light wave packets has a duration of ~1.8 fs and the delay time between them can be adjusted with attosecond precision. The researchers’ idea is that the longitudinal coherence between the two of the light wave packets can be utilized in implementing coherent control. The researchers shined Helium atoms with synchrotron radiation from the twin undulators, and generated in Helium an electron wave packet pair transcribed from the light wave packet pair. They demonstrated that the populations of the individual excited states can be controlled by adjusting the interference between the electron wave packets.
This prototypical experiment verified the novel coherent-control framework with synchrotron radiation. There is no technical restriction on the application of this coherent-control concept at shorter wavelengths to which lasers could hardly reach soon. This unexploited capability of synchrotron radiation will advance the frontier of coherent-control technology.

You need to wear a 3D glasses when you are watching 3D movies in the cinema. Can you watch a 3D movie without the glasses? If yes, how to watch 3D movies without glasses? Let’s find the solution!
What is 3D Movie?
A 3D movie actually has a separate image for each eye. When each eye sees the image intended for it (left image for the left eye and right image for the right eye), it will appear in 3D like in real life.
If the left eye sees the right image or the right eye sees the left image, it will appear flat in 2D. The purpose of the 3D viewing glasses is to cancel the wrong images so that they do not reach the wrong eye. Without the 3D glasses, both eyes see both images, and the result is a pair of flat double images without 3D vision.
How to Watch 3D Movies without Glasses?
It is not convenient for 3D movies viewers when the theaters don’t provide 3D glasses. And 3D glasses are easily to be scratched and dirty. Therefore, many 3D movies fans complaint about the glasses though they let you immerse in the films.
M.I.T. have solved that problem and created a prototype for a 3D movie theater that doesn’t require any glasses. They call it Cinema 3D which allows everyone in the theater to enjoy the same 3D experience without any glasses.
Using a complicated system of mirrors that are carefully placed and calculated based on the distance of each audience member, everyone can enjoy a movie from every seat based on the angle they’re watching without needing any accessories at all.
However, the high technology has not been applied in theaters generally. It will take some time before we all get to enjoy 3D movies without glasses.
After the Cinema 3D is normal in our daily lives, it may be possible for us to watch 3D movies through televisions. Of course, we should pay more attention and work harder to make it come true.
- How will We Watch Movies in the Future? Still in Cinemas?
- All You Need to Know about Watching Movies in VR
Technology gives us surprise and update the ways of entertainments. Theaters will apply new technology in showing movies while directors are using advanced tech in directing new movies. Thus, we will be able to watch 3D films without 3D glasses one day. And it will be a revolution in the film industry when it becomes a truth in the future.

Contact lenses are made from a soft plastic, which feels like a moisture-rich gel material. This material is called a hydrogel.
Contact lenses fit directly onto the front surface of your eye, called the cornea. They correct your vision in the same way as your glasses. Both glasses and contact lenses bend the light coming into the eye onto the retina allowing you to see clearly.
Contact lenses can be used to correct:
- Short-sightedness – when you can’t see objects in the distance clearly
- Long-sightedness – when you can’t see close objects clearly
- Astigmatism – when your eye has a rugby ball-shaped curvature
- Presbyopia – when close objects become difficult to see due to age-related changes to the crystalline lens and surrounding muscles
Contact lenses made from hydrogel are breathable and comfortable. These lenses allow oxygen through them and into your eyes, to keep your eyes healthy, as well as looking and feeling fresh.
There are many different types of contact lenses including daily, two weekly and monthly. Your optometrist will help you choose the contact lens to best suit your eyes, vision and lifestyle.

Natural (including biomedical) 3D disperse systems (DS) with nano- and/or microparticles
are inherently polycomponent polymodal polydisperse systems. Characterization of
such systems by different compatible non-destructive optical methods (refractometry,
absorbance, fluorescence, light scattering: integral and differential, static and dynamic,
unpolarized and polarized) is desirable because of feasibility to organize the on-line testing of
their state. At this road it is necessary to take into account peculiarities of inverse optical
problem solution for such complex systems (so called "three ill": "ill-defined" 3D DS, "illposed"
problems, "ill-conditioned" systems of equations). At the information-statistical
approach to the optical characterization and control of 3D DS it is possible to go round these
peculiarities and to qualify the 3D DS state changes.

A Report upon
ZAKIR UDDIN AHMAD
Student W. Tech third year Applied Electronics and Instrumentation Executive
The word laser is short for that stands for " lumination amplification simply by stimulated release of rays. " In a fairly unsophisticated sense, a laser is definitely nothing more than a unique flashlight. Strength goes in, usually in the form of electrical power, and light comes out. However the light released from a laser differs from that coming from a flashlight, and the variations are well worth discussing. You could think that the biggest difference is that lasers are more powerful than flashlights, yet this conceiving is more frequently wrong than right. True, some lasers are significantly powerful, but many are much less strong than even the smallest torch. So electrical power alone is not a distinguishing characteristic of laser mild. But for at this point it's enough to say that we now have three dissimilarities between lumination from a laser and lightweight from a flashlight. 1st, the laserbeam is much less wide than a flashlight beam. Second, the white light of a flashlight column contains numerous colors of sunshine, while the light from a laser includes only one, pure color. Third, every one of the light waves in a laserbeam are in-line with each other, while the light surf from a flashlight happen to be arranged at random. The significance of the difference will become apparent as you read about the size of light. Lasers come in almost all sizesвЂ”from little diode lasers small enough to fit in the eyes of a filling device to huge military and research lasers that load a three-story building. And different lasers can produce many different colors of light. The " light" produced by carbon dioxide lasers and neodymium lasers cannot be seen by the eye because it is inside the infrared percentage of the range. Interestingly, few of these lasers produce whilst much power as a typical 100-W lightbulb. What's more, lasers are not actually very successful. To produce 1W of light, almost all of the lasers listed in Table 1 . 1 could require hundreds of w of electricity. What makes lasers worthwhile for a lot of applications, however , is the thin beam that they produce. A fraction of the watt, packed into a supernarrow beam, can easily do things not any lightbulb could ever do. The ruby, yttrium aluminum garnet (YAG), and glass lasers are solid-state lasers. The light is generated in a solid, crystalline fly fishing rod that looks much just like a cocktail swizzlestick. All the other lasers listed are gas lasers, which make light within a gaseous channel like a fluorescents sign. If perhaps there are solidstate lasers and gaseous lasers, it's rational to ask if perhaps there's this sort of a thing as being a liquid laserlight. The answer is yes. The most common case is the organic dye lazer, in which absorb dyes dissolved in a liquid produces the lazer light. Laserlight Technology are useful for a wide variety of real time applications dealing with massive amount data. Several of its applications are used in waveguides, just like optical fibres. Spectroscopy photochemistry, atomic vapor laser isotope separation, and optical marketing and sales communications. So in this report a general idea about laser is given to you.

NIR Systems at Celignis
We have two FOSS XDS NIR spectrophotometers in our laboratory. These both contain an XDS monochromator which is attached, for one system, to a rapid solid content analyser (RCA) module and, in the other system, to a rapid liquid analyser (RLA) module. Specifications of the XDS monochromator and each of these modules are detailed below:
This system uses a tungsten halogen filament lamp as the radiative source. Light then enters the monochromator enclosure via the lamp housing exit slit and is directed onto the grating by a mirror after the entrance slit.
The grating is a concave holographic grating, ruled with fine lines to separate the white light into individual wavelengths. It is rotated by a positioning motor, and hence the rotational position is correlated with the wavelength. The resolution of the grating is specified as 0.5 nm. An effect of the diffraction grating is that many orders of radiation are produced, each one comprising a spectrum over a certain angle. There occurs a partial overlap of the different orders of radiation which will result in different wavelengths from different orders appearing in the same position. For example, the wavelengths 2400 nm, 1200 nm and 800 nm from the 1st, 2nd and 3rd orders, respectively, might be superimposed. The XDS only uses first order radiation, since this is the most intense. Hence, it is necessary to block the radiation from the other orders. This is accomplished with order-sorter filters which are mounted in a paddle whose position is kept in sync with the grating position motor. Hence only first order radiation is let through. The four filters are: 400-700 nm, 700-1100 nm, 1100-1700nm, and 1700-2500nm.
The light leaves the grating and is reflected towards the order sorter filter off of a second mirror. The light then passes through the order sorter and fills the exit slit with the selected light to pass, via optical fibre, to the detector module. Other relevant specifications of the XDS monochromator are detailed below:
- Spectral Resolution - This can be determined as the measurement of the separation of closest pair of absorption lines that can be separately identified. It is reported to be 2 nm for the FOSS XDS.
- Spectral Data Interval - The gaps over which data points are collected, in the XDS it is every 0.5 nm.
- Wavelength accuracy - The difference between the measured wavelength of a wavelength standard and the wavelength reported for that standard by the equipment. This is reported as being less than 0.05 nm for the FOSS XDS.
- Wavelength precision - Repeatability of wavelengths on the same instrument, given as < 0.005 nm on the XDS. Wavelength precision can also be measured based on a group of instruments in which case the value for the XDS is reported as <0.02 nm.
- Scan speed - Time taken to cover all the analytical wavelengths. The XDS has a data acquisition rate of 2 scans per second.
- Stray light - This is the sum of any energy/light, other than the chosen wavelength, that reaches the detector. It is reported to be < 0.1% at 2300 nm for the XDS.
Rapid Content Analyser
The Rapid Content Analyser (RCA) has a reflectance detector that incorporates 4 silicon detectors (for the wavelength range 400-1100nm) and 4 lead sulphide detectors (for the wavelength range 1100-2500 nm). These detectors are mounted at a 45 degree angle to the sample surface (which is irradiated by the light at normal incidence). The signal from the detector is then sent to the amplifier where it is amplified and, digitised, and sent to the computer associated with the system.
In a conventional set-up an iris is locked in place in the RCA module and used to focus a small circular cell over the scanning window so that spectra can be collected from the sample contained within this cell. The capacity and surface area of this cell are very small and would preclude the analysis of anything but well comminuted and homogeneous samples. This would prevent the development of NIR analysis methods for more hetereogeneous samples that have larger particle sizes. The RCA transport assembly solves this problem by allowing material within a much larger sample cell, the 'coarse sample cell', to be scanned. This rectangular cell is placed in the locking mechanisms of the wheeled solids-transport device and spectra are taken through the window. The transport assembly then moves, by means of a motor device, to a second position, which represents a separate part of the coarse cell to that which was previously scanned, and further spectra are collected. This process repeats six more times and at the final iteration the last part of the window of the coarse sample cell has been scanned and the transport assembly then returns the cell to its starting position.
Rapid Liquid Analyser
This system is designed for the analysis of liquids and includes a transmission detector and the capacity to include a variety of analytical cells of differing path-lengths. The system also includes a heater to allow for a set temperature to be reached before the spectrum is taken.

Who Invented the Microscope? The first microscope was invented in 1590 by the Dutch Zacharias Janssen. This inventor created the optical microscope composed of two lenses. He developed this instrument with lenses that were made by his family. The microscope was a great innovation for those times, for being an instrument that allows us to see objects or organisms that are too small to be observed by our eyes.
The term microscope comes from the combination of two Greek words like micros which is “small” and scope which means “to look“, for what it describes this object is capable of observing really tiny objects.
The branch of science that studies very small objects with microscopes is called microscopy. Janssen’s microscope had as dimensions a tube 45 centimeters long and 5 centimeters thick. It also had a convex lens on each side, in order to have a magnification of the observed object between 3 and 9 times depending on the aperture of the diaphragm.
Who Invented The Microscope In Which Year?
This first microscope was optical because it contained two lenses. This apparatus was capable of generating a larger image of the object that was observed and operated by refraction.
The development of the microscope allowed science and scientific research to advance a lot since from this invention it was possible to study important objects invisible to human sight. Before the microscope, these types of studies could not be done exactly, because they were not visible. With the microscope, it was possible to observe structural, cellular, and component aspects found in people, animals, plants, rocks, and in all kinds of living and even inert organisms.
Before the invention of the microscope, it was not known how the smallest structures in nature were or how they worked.
Another important advance occurred in the year 1665 when it is described in a text by William Harvey how he used the microscope to observe blood capillaries. Sometime later Robert Hooke used the microscope to look at a thin piece of cork and was able to see that the material was porous and that it looked like small cells that he named cells.
- This was the first observation of dead cells in history and all thanks to the microscope.
- Robert published a text called Micrographia, with drawings describing the images obtained with light microscopy.
- After a few years, the Italian biologist and anatomist Marcello Malpighi was the first to observe cells and living tissue with a microscope.
- During the 17th century, Anton van Leeuwenhoek developed his own microscopes and managed to describe and document several relevant discoveries, such as the observation of red blood cells, bacteria, protozoa, sperm, which until then had not been seen or analyzed in detail.
In order to observe these objects, Leeuwenhoek carved his own magnifying glasses and obtained a microscope at 275 times magnification. This man went on to create 26 different microscopes throughout his life.
Leeuwenhoek became a major microscopist even though he had no scientific training. Also for his research and discoveries, he is considered the founder of bacteriology.
Microscopes with association achromatic objective lenses were developed in the 18th century, with Chris Neros and Flint Crown being the first to use them. Then in the 19th century, it was discovered that dispersion and refraction can be changed by using two or more optical means. Thanks to this knowledge, excellent quality achromatic objectives could be developed that improved microscopes.
- At this time mechanical improvements were achieved that increased stability and simplicity for the use of microscopes. In 1877 Ernst Abbe managed to improve microscopy since he replaced water with cedar oil, so he was able to reach 2000 times the observed objects.
The Electron Microscope
- Between 1925 and 1932 the first electron microscope was created, designed by Ernst Ruska and Max Knoll.
- With this new microscope, greater magnification of the objects was achieved.
- The improvement in microscopes was achieved because the electron beam instead of visible light began to be used to focus the sample to be observed, therefore, 100,000-fold magnification was achieved.
- Electron microscopes magnify objects much more because electrons have a shorter wavelength than visible photons.
Types of Microscopes
Microscopes can be classified into simple, which are those that only use one lens to enlarge what you want to observe, and compounds, that use two or more lenses to enlarge the sample.
- These are the most common types of a microscope but there are still other typologies. Currently, there are many types of microscopes such as light microscopes, light microscopes, electron microscopes, scanning probe microscope, atomic force microscope, virtual microscope.
- There are other typologies that are used in scientific research, but they are less used. The most modern microscopes are digital.
- These microscopes are connected to a computer through a USB port which allows you to see what appears under the microscope on the computer.
The images are converted into files and saved on the computer. The rest of the microscope’s operation is the same as the rest.
Modern microscopes are made up of a set of elements such as lenses, mirrors, and prisms that transmit light from the objective to the eyepiece. These will be different according to the type of microscope in question, but basically they share the same components.
Download App: Microscope – Apps on Google Play
Currently, all kinds of elements such as bacteria, organisms, the composition of rocks or fluids, cells, and all kinds of really small objects found in nature can be analyzed with microscopes.
Science has come a long way thanks to the microscope since not only can you observe the components of biological objects, but you can also observe the functioning and interaction between organisms, cells, and biological substances.

The microscope is a fundamental instrument for current scientists since it allows them to discover new knowledge constantly, which favors the understanding and understanding of certain topics, and in this way, they can solve problems especially in the medical and biological areas.


LED matrix is a type of display made up of many individual LED (Light Emitting Diodes) that can be used to create graphic or text displays. The LEDs are arranged in rows and columns, allowing them to be individually addressed and creating dynamic visuals very easily.
How does the LED matrix work?
A LED matrix is a two-dimensional array of LEDs, usually arranged in rows and columns with each LED capable of independently emitting light. It can be used for a wide range of display purposes including digital signage, passcode locks and more.
The way the LED matrix works is by applying current to each row and column of the array in the desired order. For example, if you wanted some LEDs in the top left to be lit, then you would apply a current to each row one after another while keeping the column pin high at all times. This will cause the desired LEDs to light up while all other LEDs remain off.
What is the advantage of LED matrix?
The main advantages of LED matrices are their bright illumination and low power consumption when compared to other types of displays. Additionally, they are highly customizable and can be reprogrammed to display different images, animations, and messages. Furthermore, they are relatively inexpensive and require fewer components than other types of displays.

Reflecting Telescope Definition; Reflecting telescopes (also known as “reflectors”) employ a single or many sets of curved mirrors to reflect light and produce images. A remedy for the refracting telescope’s chromatic distortion was devised by Isaac Newton in the 17th century: the reflecting telescope.
In spite of the added optical aberrations, reflecting telescope design allows for enormous objective sizes. A reflector is the most common type of big telescope in astronomy. Additional optical components can be added to improve image quality or to better place the image mechanically in a reflecting telescope in a number of combinations. Reflecting telescopes are sometimes known as catoptric telescopes since they use mirrors.
Mirrors were mostly made out of metal from Newton’s time until the 1800s. The Leviathan of Parsonstown, which included a 1.8-meter-wide metal mirror, is included in this category, as are Newton’s original concepts and the largest telescopes of the nineteenth century. Using a block of glass coated with a very thin layer of silver, a new method gained favor in the early nineteenth century.
Reflecting telescopes like Crossley and Harvard were made possible in part by common telescopes, and this helped raise the status of reflecting telescopes in the scientific community when metal mirror designs were exposed for their flaws. Metal mirrors, in particular, reflected around 23% of the light, and the metal itself was tarnished as a result. The mirror’s needed accuracy figure may be lost with frequent cleaning and tarnishing.
The visible spectrum of light is primarily focused and converged by an optical telescope (while some work in the infrared and ultraviolet). The brightness and angular size of distant objects are magnified with optical telescopes.
Direct observation or photography, as well as data collection via electronic image sensors, are possible with an optical telescope.
One or more curved optical components, such as glass lenses and mirrors, are used to gather and concentrate light, allowing the image to be captured, photographed, analyzed, and transmitted to an electronic device.
Several non-astronomical types of equipment, such as theodolites and spotting scopes, as well as camera lenses and spy glasses, all use a telescope as their primary source of light. By focusing visible light through a telescope’s eyepiece, a magnified image is formed. The phrase “sky binocular” is most often used to describe a monocular mounted on a tripod for viewing the night sky, but portable binoculars may be used for a wide range of tasks.
Refracting, reflecting, and compound telescopes are the three main types of optical telescopes.
Look at the accompanying figure, which demonstrates the difference between refracting and reflecting light.
If you’re looking for the word refractor telescope, you’ve found it. As the name suggests, this is an optical telescope that uses a lens in order to take an image. In addition to spy glasses, astronomical devices, and long-focus camera lenses, this telescope is employed. By multiplying the focal length of the telescope’s eyepiece with the focal length of the objective lens, a refractor’s magnification is calculated.
The telescope’s eyepiece or instruments, which are used to focus the telescope’s image, are often positioned in the back, after a lengthy tube and a lens. The hole in the design might be as small as a few centimeters for small spotting telescopes or as large as one meter for the largest refractor ever built. Unique components may be found in the design as well as the eyepiece. Spotting telescopes with an eyepiece that has an extra lens can keep the image from looking upside-down.

Processes & Tools: Active Alignment for Camera Modules and Opto-Electronics
Active alignment measures key performance attributes in a product during manufacturing enabling dynamic adjustments of the manufacturing process to create products with optimal performance. This is different from passive alignment, where components align to each other based on the accuracy and precision of mechanical fixturing, tooling, and motion stages in the manufacturing process. AEi typically implements a multi-axis, also called a multiple degree of freedom, approach to active alignment. This allows us to compensate for variation of component tolerances in multiple physical dimensions for best overall results.Application Examples:
- Camera Sensor Alignment and Test
- Planar Photonics Device Alignment and Test
- Single Channel Photonics Device Alignment and Assembly
Products & Platforms:
- Photonics Module Align, Assembly and Test (PMAT)
- Camera Module Align, Assembly and Test (CMAT)
Features & Benefits of AEi Implementation:
- Open architecture approach allows for selection of optimal instrumentation and sensors for a given application
- The FlexAuto software platform allows measurements and dynamic adjustments based on these to be easily configured
- Product performance and yield are almost always greatly improved using active alignment versus just passive alignment
While active alignment requires additional instrumentation and sensors, etc., it may not necessarily be more expensive than passive alignment. Active alignment supports the use of less accurate (and less expensive) fixturing and motion stages in a given manufacturing station.
As with other tools we use, AEi takes an open architecture in utilizing active alignment. We have the experience and ability to select sensors and instrumentation to include in our flexible automation solutions to best meet a given application’s needs. This includes a wide range of optical and electronic instruments, force transducers, flow transducers, and temperature transducers. Our reconfigurable station control software is used to acquire the measurements and optimize the manufacturing process to make active alignment practical and cost effective.
