Infrared sensing principle People have always known: 1. Many materials can absorb infrared radiation (due to intramolecular vibration) 2. For any material, its absorption capacity changes with the change of wavelength (its absorption spectrum) 3. Different materials have different absorption spectra The basic principle of infrared gas sensor operation is to rely on the discovery of the above facts. Table 1 shows typical infrared spectra, including carbon monoxide, propane, hexane, and carbon...
Video optical transceiver is a device that converts 1 to multiple analog video signals through various codes into optical signals for transmission through optical fiber media. Since the video signal is converted into optical signals, there are two technologies: analog conversion and digital conversion. Therefore, video optical transceivers are divided into analog optical transceivers and digital optical transceivers. The principle of the optical transceiver is to modulate the signal to the...

Optical lenses are divided into spherical lenses and cylindrical lenses. The curved surface of the spherical lens is a part of the spherical surface, and is divided into a convex spherical lens or a concave spherical lens according to the polymerization or separation of the parallel light. The convex spherical optical lens is used to correct hyperopia, presbyopia or aphakic body. The concave spherical lens is used to correct myopia. The curved surface of the cylindrical lens is part of the...

Theme: Industry In the current lighting industry, LED lighting is the latest industry. All sectors are full of strength to actively develop LED-related lighting. Of course, the prerequisite for LED lighting must be the brightness and color temperature of LED itself. Power supply and heat sink, the key to the final success or failure is the light shape emitted by the LED. How to effectively control the refraction of the LED light shape, the secondary optical lens is the key. Redditch Optics Co.,...
The most classic of the standard lenses is the conical lens. A large part of these lenses rely on total internal reflection and are called TIR (Total Internal Reflection) lenses. Usually the TIR lens is an axisymmetric design that provides a beautiful circular spot that can be combined into multiple LEDs to form an array lens or a single holder for easy installation and light control. TIR lens VS reflector In fact, the basic working principle of the two is the same, but the TIR lens has more...
The act of selling counterfeit lenses under the ZEISS brand not only disturbed the normal market order, but also seriously damaged the legitimate rights and interests of consumers. On the occasion of the annual 3.15 Consumer Rights Day, Carl Zeiss Optics (Guangzhou) Co., Ltd. cooperated with the relevant national functional departments to carry out nationwide anti-counterfeiting actions in response to counterfeiting and counterfeiting on the market. The anti-counterfeiting campaign aims to...
The general industrial lens does not have the magnification factor because the general industrial lens has a different magnification when used at different working distances. At this time, we need to calculate the focal length (f) of the lens and the working distance (WD) of the lens. . 1.1 Magnification (X) The magnification X of the optics is used to describe the ratio of the image size (h') to the object size (h): X=h'/h Generally when imaging with a camera with an industrial camera, the...
At present, in China's large-scale surveillance camera project areas, natural conditions such as rain, steam, haze and other natural conditions easily lead to ambiguity in monitoring, and even in severe cases, there is only a white mist. The fog problem has become a weakness of monitoring equipment. However, in the special monitoring projects, it is very necessary to solve the fog problem, so the current monitoring project puts forward new requirements for the fogging technology. At present,...
