Optical glass filter is an important optical element, widely used in various optical systems, used to selectively transmit or reflect specific wavelengths of light, so as to achieve the control of the spectrum. Optical filters can be classified according to different characteristics, according to the spectral band can be divided into ultraviolet filters, visible light filters and infrared filters; According to spectral characteristics, it can be divided into band-pass filter, cut-off filter, spectroscopic filter and neutral density filter. According to the film layer material can be divided into soft film filter and hard film filter. The working principle of optical filter mainly includes absorption filter, interference filter and diffraction filter. The absorption filter uses the absorption characteristics of specific materials to filter. The interference filter makes use of the optical interference effect of the multilayer film to make the specific wavelength of light reflect and refract several times in the film, so as to realize the selective filtering of light. Diffraction filters use the diffraction principle of light, by marking a specific pattern or structure on the surface of the filter, so that the light diffracted when passing, to achieve the selection of a specific wavelength. The main parameters include center wavelength (CWL), half bandwidth (FWHM), peak transmittance (TP), Blocking and cut-off band.
