Green filters transmit a relatively narrow wavelength band centred around light in the green spectrum and are named after the wavelength at which their transmittance attains the maximum value. When desiring to attain the maximum transmittance at a specific wavelength, or to absorb light and shorter wavelengths, bonding these filters and sharp cut filters together will serve the purpose.

Green filters are used as contrast-effect filters for black and white photography, and also as 3-colour separation filters.
