Colored Glass Filters
COLORED GLASS FILTERS
Green Filters (G)
Green Filters transmit a relatively narrow wavelength band centered around light in the green spectrum.
They are used as contrast-effect filters for black and white photography, and also as 3-color separation filters.
Bond these filters and sharp cut filters together to attain the maximum transmittance at a specific wavelength or to absorb light of shorter wavelengths.
