Optical properties of quartz glass
The optical properties of quartz glass are unique. It can pass through the far-ultraviolet spectrum, and is the best for all UV-transparent materials, as well as visible and near-infrared. The user can arbitrarily select the desired variety from the range of 185-3500 mμ band as needed. Due to its high temperature resistance, quartz glass has a very small thermal expansion coefficient and good chemical thermal stability. Bubbles, stripes, uniformity and birefringence are comparable to those of ordinary optical glass, so it is a highly stable optical system t
Infrared sensor camera technology, infrared lens
British astronomer Herschel discovered infrared technology in 1800. In the constant efforts of the scientific community, infrared technology has also been applied to various occasions. The most typical one for security applications is the infrared camera. Infrared cameras can be divided into 2 categories, analog infrared cameras and infrared network cameras. But they all have the same characteristics, which are mainly manifested in the different characteristics of infrared light source and the choice of low

Innovative dual-band bandpass filter design
Modern communication systems often use dual band bandpass filters to isolate different operating bands in the same network. The traditional design dimensions of such filters are relatively large and require an additional combined network for the two filters. However, the dual-band bandpass filter design method discussed in detail in this paper can be made very small. Its structure is relatively simple, consisting of two asymmetric split spiral resonators (ASSR) cascaded with a microstrip line. Due to the inherent spiral geometry of the ASSR, the ASSR can be

Lens design method for LED light source
The optical component is a very precise component, and the manufacturing cost is high. If the thickness of the component can be reduced, or even a sheet lens, the size of the optical component can be reduced, thereby reducing the size of the lamp or other equipment, and saving material. cut costs. As the thickness is reduced, the light absorption is also reduced, and the efficiency of the luminaire or instrument is also increased. Therefore, it is one of the goals of optical design to make high-quality sheet-shaped optical parts.
The difference between laser glass and ordinary optical glass
[China Glass Net] The main advantages of laser glass compared to laser crystals are: (1) Easy to prepare. By applying the process technology for preparing optical glass and improving it, it is possible to obtain a highly transparent and optically uniform glass, which is relatively easy to produce a large-sized work substrate material, and has a low cost, and a large volume and a high density of activated particles are used for high power. And important advantages of high energy lasers.
Band pass filter frequency introduction
A bandpass filter is a filter that can pass a frequency component in a certain frequency range but attenuate other ranges of frequency components to an extremely low level, as opposed to the concept of a bandstop filter. An example of an analog bandpass filter is a resistor-inductor-capacitor circuit (RLC circuit). These filters can also be generated using a low pass filter in combination with a high pass filter. An ideal bandpass filter should have a completely flat passband that is not amplified or attenuat
Difference between normal lens and infrared optics lens
Why do the same focal length lenses also divide the ordinary lens and infrared lens? What is the difference between a normal lens and an infrared lens? Next, we will briefly explain the difference between the two: First of all, the purpose of the two is different: In a monitoring environment that does not require infrared light subsidy, an ord
Centerless cylindrical grinding It does not have a head frame and tailstock, but the workpiece and the guide wheel support the workpiece, grinding with a grinding wheel. Unintentional grinding method It is composed of three mechanisms: grinding wheel, adjusting wheel and workpiece support. The grinding wheel actually works as grinding. The adjusting wheel controls the rotation of the workpiece and the workpiece feed speed occurs. The workpiece holder is grinding. Hold the workpiece while cutting. The centerless cylindrical grinder has a high productivity and
The optical effect and application difference between the lens and the reflector
There is a famous saying: optics is the soul of lamps (not optical is the bullet of LED?). What if a lamp has no soul? Then I have to sell hardware, aluminum plate, lamp housing, LED "breaking jin ~" (Cantonese, meaning by weight). So the question is, what do we use to shape the soul of LED lamps? LED common optics are lenses and reflectors. What are their advantages and disadvantages? Xiong Da is here with you: lens The LED lens is divided into a primary lens and a secondary l

How to clean the camera lens ? cleaning camera lens maintenance tips
How to clean the camera lens cleaning camera lens maintenance tips The lens is the "window of the mind" of the digital camera. The good lens can ensure high-fidelity, high-contrast images. Since the lens of the digital camera is difficult to replace, and the maintenance cost is high, pay attention to keep the lens clean. Become very important. However, after using a digital video camera to go out, the lens of the camera will inevitably be stained with dust and other dirty things. Sometim

The difference between the imaging properties of concave mirror and convex mirror
Before introducing the difference between the imaging properties of concave mirrors and convex mirrors, the concepts of concave mirrors and convex mirrors are known. Concave mirrors are reflection imaging. A mirror (including a convex mirror) is not an instrument that transmits light but is reflected back to the image, and the light follows the law of reflection. This type of mirror is called "convergence" because they tend to collect the light that strikes the surface, and the parallel incident light will be re-aggregated at the focus, also because the norm
China's CCTV lens market is a huge market, attracting the attention of countless world-class lens manufacturers. Many years ago, the Chinese CCTV lens market was mainly based on Japanese Seiko lenses. As long as it was engaged in the CCTV monitoring industry, few people did not know Seiko. Before 1999, the Chinese market can say that more than 70% of imported CCTV lenses are Seiko lenses, and most of the domestic lenses are mainly imitation Seiko products. But in recent years, the market pattern has changed. Because CCTV Seiko has implemented a general agenc
Optical experts talk about how optical lenses are recognized?
At present, optical experts have analyzed that the types of spectacle lenses are roughly divided into five types: anti-reflective protective lenses, colored lenses, painted lenses, polarized lenses and color-changing lenses. 1. Anti-reflective protective lens This kind of spectacle lens is coated with a thin layer of magnesium fluoride to prevent strong light reflection, so that you can see things more clearly and not interfere with strong light. To check if your glasses are really anti-reflective lenses, yo

What kind of lens is the best lens? From the appearance to identify the advantages and disadvantages of the surveillance lens, the main attention to the following points: First, look at the exquisite degree of surveillance lens appearance; second is to feel the monitor lens feel, the third is to see the coating, feel the amount of light through the monitor lens. These are just a basic understanding of surveillance cameras from the outside. So, from the lens parameters, how should we interpret the surveillance
