Product Family Description

  • 710nm Cut-Off Wavelength
  • Circular and Rectangular Options
  • Various Sizes Available

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 cut-off filters to eliminate the effects of the presence of near infrared light incident upon the detector.
