Filtered Diffraction Gratings

Our patented filtered diffraction grating is a custom solution for OEM applications requiring isolation of the desired spectral band prior to diffraction, and are design limited in doing so prior to the diffraction grating component. Filtering the undesired spectral band prior to diffraction minimizes second order and ray scattering effects, maximizing spectral dynamic range.

  • Block undesired spectra before dispersion
  • Reduce number of optical components
  • Reduce system size
  • Designs for reflection and transmission diffraction gratings

Optometrics develops hybrid grating and optical filter for holographic weapons sight.
