Gratings for OCT

The clearest, deepest spectral domain optical coherence tomography (SD-OCT) images require an optical design that covers a broad bandwidth with maximum signal to noise. That’s why we developed our HD gratings to have high efficiency for all polarizations, even at the extremes of a 100-200 nm operating wavelength range. Choose from our range of stock gratings, or draw on our expertise in OCT to design your ideal grating. Our OEMs trust us to work closely with them from initial concept to product launch, supporting volumes of tens to thousands.


  • Patented broadband high dispersion designs
  • Excellent 1st order diffraction efficiency for greater sensitivity and faster scan rates
  • Superior uniformity over the full spectral band
  • Minimal polarization dependence
  • Low scatter & AR coating minimizes stray light
  • Robust, durable design for easy cleaning
  • Enables compact, transmissive optical designs
