Filters are made by adding special dyes to a plastic or glass substrate or by evaporating an optical film on the surface to attenuate (absorb) certain bands of light in a wave or by accurately selecting a small band through which to reflect or absorb other unwanted bands. By changing the structure of the filter and the matching parameters of the membrane structure, various spectral characteristics can be obtained, so that the filter can control, adjust and change the transmission and reflection state of light waves. Its advantages are: peak transmittance, flat band spectrum, excellent cutoff in a wide band range, and good wet temperature stability.
