Product Family Description

  • Prevent Unwanted Reflection Towards the Light Source
  • Spectrally Flat
  • VIS and NIR Ranges Available

Our Non-Reflective Neutral Density Filters are designed to evenly attenuate a light source while preventing unwanted back reflections. A proprietary coating design minimizes reflection to less than 2%, while maintaining very high neutrality over the entire design spectral range. Available for visible applications from 400-700nm or NIR applications from 700-1200nm, the filters are ideal for limiting the transmission of broadband halogen, fluorescent, and tungsten sources, as well as low power lasers.

Non-Reflective Neutral Density Filter Kits

Each kit includes 10 filters in optical density values of 0.3, 0.5, 0.6, 0.9, 1.0, 1.3, 1.5, 2.0, 2.5, and 3.0. The kits are ideal for determining precise system optical density requirements.

Custom densities are available for OEM applications.
