The difference between laser glass and ordinary optical glass The main advantages of laser glass compared to laser crystals are: (1) Easy to prepare. By applying the process technology for preparing...
How much do you know about the classification of optical glass? Optical Classification 1. Colorless optical glass There are specific requirements for optical constants, such as high visible light...
The band-pass filter is a too broad concept, narrow-band broadband, LC/microstrip/coaxial/waveguide/medium. Various patterns of resonators, various patterns of coupling structure. However, no matter...
Aspherical parts superfine machining skills 1 Overview 1.1 The effect of aspherical optical parts Aspherical optical parts are a very important optical part; commonly used parabolic mirrors,...
A band-pass filter is a device that allows waves of a specific frequency band to pass while shielding other frequency bands. For example, the RLC oscillator circuit is an analog bandpass filter. A...
It is well known that the optical glass lens processing industry is a very demanding industry, and the standards of the production workshop or the production process must be controlled (for example,...
At this stage, under the situation of increasing global energy shortage, energy conservation and consumption reduction has become a serious problem that we have to face. While the lighting system...
Because now the energy used by the earth is mainly non-renewable oil. Therefore, many scientists are committed to the development of a variety of renewable energy sources to ensure the daily supply...
1 Overview 1.1 The role of aspherical optical components Aspherical optical components are a very important optical component. Commonly used are parabolic mirrors, hyperbolic mirrors, ellipsoidal...
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...
