Optical glass can change the transmission direction of light and the relative spectral dispersion of ultraviolet, visible or infrared light. Optical glass has stable optical

Optical lenses usually have low transmittance after precision polishing, and can only be used after coating. Coating is a process of overlaying the film material

Single lens is a lens composed of pure single elements, which can be considered as the basic element for developing optical systems. Based on the

The polarized beam splitting prism can divide the incident non-polarized light into two perpendicular linearly polarized light. P polarized light passes through completely, S polarized

Filter is widely used in fluorescent microscope, so the design of many filters is determined according to the requirements of the microscope manufacturer. Users can

With the climax of AI in China, face recognition technology has developed rapidly. Relevant institutions predict that the market size of face recognition will reach

Optical glass refers to glass that can change the transmission direction of light and the relative spectral dispersion of ultraviolet, visible or infrared light. Optical

Germanium is a relatively common optical material. It can be used not only in long-wave infrared, but also in medium-wave infrared. Germanium should be treated

The optical window slice is used as a viewport to protect optical components, instruments or other components in the laser. In some applications, optical window

So far, we have discussed the direct measurement of the optical properties of the filter, but there are still some natural properties of objects that
