IR cutoff Since common light sources deliver light that has a very broad spectral output, reaching beyond the visible, many visual and detector-based applications call for an infrared filter that is designed to pass only light within the visible spectrum. For example, monochrome cameras are often used with IR cutoff filters to eliminate the effects of the presence of near infrared light incident upon the detector.
