Longpass filters
General description:
Interference filters are based on the phenomenon of light interference. The light of a given wavelength passing through the longpass filters is amplified, and the light intensity of other wavelength ranges is weakened or extinguished.
These type of filters are used when we want to select a relatively narrow band from the light with a continuous spectrum. We have to isolate a line appearing at a specific wavelength from exciting light with a linear spectrum. Their transmittance depends on the angle of incidence of the incident light.
