The substrate materials of the colour filters inherently have different absorption and transmission properties across the spectrum.The are often used as long-pass and band- pass filters.It should be noted that the boundaries between passing and blocking wavelengths are less sharp than most coated filters,although peak transmission is often considerably higher.
