Optical lens is an indispensable component in the machine vision system, which directly affects the quality of imaging, affecting the implementation and effect of the algorithm. Optical lens from the focal length can be divided into short-focus lens, medium-focus lens, telephoto lens;

Advanced Driver Assistance Systems, that is advanced driver assistance system, referred to as ADAS, is the use of a variety of sensors installed in the car, the first time to collect the car's environmental data, static, dynamic object identification, detection and tracking technology Processing, which allows the driver in the fastest time to detect possible danger.

Sports DV camcorder is designed for outdoor sports records, is able to skydivers, diving, surfing, skiing, racing and other rights movement in the wonderful sleep clearly recorded, however, as many brands of various types of sports DV market, if not specifically understand their application scenarios, want to pick out a suitable for their own sports DV is not a simple matter, today Xiaobian elaborate sports DV camera that thing.

Law enforcement recorder, also known as police law enforcement recorder or on-site law enforcement recorder. Digital camera, digital camera, talkie transmitter function in one, to the law enforcement process of dynamic, static scene of the digital records, to facilitate the police officers in a variety of environments in law enforcement use.

Chemical composition and optical properties of similar glass, also in the Abe map is also located in the adjacent position. Shabu glass factory Abeto has a set of straight lines and curves, the Abbe is divided into many areas, the optical glass classification; such as crown glass K5, K7, K10 in the K area, flint glass F2, F4, F5 in the F Area.

Prism: The two lenses that are not parallel to each other because they have the property of translating the image to the tip to treat certain ocular diseases. Lens: The lens is divided into spherical lenses and lenticular lenses. The ball lens is a part of the spherical surface, according to its parallel light polymerization or separate ...

1: Refractive index optical glass lens according to the refractive index can be divided into crown glass (refractive index of 1.49 to 1.53) flint glass (refractive index of 1.60 to 1.9), the refractive index directly affects the thickness of the lens, that is, The higher the lens, the thinner the lens. The refractive index of the resin sheet is between 1.49 and 1.76 ...

The raw materials for the production of optical glass are oxides, hydroxides, nitrates and carbonates, and phosphates or fluorides are introduced according to the requirements of the formulation. In order to ensure the transparency of the glass, must strictly control the content of colored impurities, such as iron, chromium, copper, manganese, cobalt, nickel and so on. Ingredients ...

Glass lenses, with more than other materials, more scratch-resistant properties of the lens, but the relative weight of its sink, the refractive index is relatively high: ordinary film is 1.523, ultra-thin film: 1.72 or more, up to 2.0. The main raw material of glass lenses is optical glass. Its refractive index than the resin mirror ...

Colorless optical glass has certain requirements for optical constants, with high visibility through the visible area, no selective absorption of coloring and so on. According to the size of the Abbe number is divided into the crown and flint glass, all kinds of high and low according to the refractive index is divided into several kinds, according to the size of the order of refraction. Used as a telescope ...

The difference between optical glass and other glass is that it must meet the requirements of optical imaging as an integral part of the optical system. Therefore, the determination of the quality of optical glass also includes some special and more stringent indicators. There are the following requirements for optical glass:

Rare earth element optical glass appeared in the thirties of the new rare earth element optical glass, the main component is lanthanum, thorium, tantalum oxide. Rare Earth Elements Optical glass has a high refractive index, opening up new possibilities for the design of optical lenses. Today there are many large-aperture lens lanthanum glass. Thorium glass

Monocular lenses that are single focus optical lenses, is the most widely used optical lenses. 1, glass lenses have a more scratch-resistant properties than other materials, but the relative weight of the sink, the refractive index is relatively high: ordinary film is 1.523, ultra-thin film: 1.72 or more, the highest ...
