Filter plate  Technical specifications

Filter plate characteristic

Thin film filter, generally through a longer wavelength, used as infrared filter. The latter is on a certain substrate, with the vacuum coating method to alternately form a certain thickness of high or low refractive index of metal - medium - metal film, or the full medium film, to form a low-level, multi-level series solid Fabry-Perot interferometer. The choice of the material, thickness and series mode of the film layer is determined by the required central wavelength and transmission bandwidth λ.
