TECHSPEC® OD 6.0 Rugate Notch Filters

  • Low Ripple, No Harmonics
  • 92% Transmission from 350-2000nm
  • OD >6 Rejection for Center Wavelength

These notch filters offer superior transmission for a broad range of wavelengths combined with OD > 6 blocking at the center wavelength. Rugate style notch filters feature a single coating layer with a continually varying refractive index offering superior performance over standard notch filters. Rugate notch filters feature low ripple and no harmonic reflections making them useful for a broad range of wavelengths. Each filter is mounted in a black-anodized aluminum ring.
