What is the principle of optical Prism
Prism is a very important application component in the field of optics. After years of development and derivation, it has become an optical component product in various application fields. What is the principle of optical prisms? What are the main types? Let the editor of Maipu introduce to you.
An optical prism in optics is a transparent optical element whose polished surface refracts light. The correct surface angle depends on the application requirements. However, in general, materials that are transparent to wavelengths can be used to manufacture optical prisms, but traditionally and external optical prisms are usually manufactured using K9L and a quartz substrate.
Prisms can separate light into original components, spectra, and can also be used to reflect or separate light into different polarizations.
When light moves from one medium to another, its speed will change, its path will bend, and part of the light will be reflected. The ratio of the angle change and reflection of the beam at the interface depends on the refractive index of the two media. The refractive index of most media is related to the wavelength or color of light. Sometimes only the surface of the prism is used for reflection rather than dispersion. If the light inside the prism reaches the surface at a steep angle, total reflection will occur, and all light will be reflected back into the prism.
