Use transmission gratings to angularly disperse light by wavelength and benefit from our proprietary fabrication method that delivers both economy and superior performance.

These gratings feature high diffraction efficiency (95% typical) and low polarization-dependent loss (PDL), minimizing losses particularly in multipass designs. Their high optical damage threshold is ideal for use with high-energy pulsed and CW laser systems.

Transmission Gratings – Some Key Specifications

Use gratings supporting both S and P polarizations over the operation wavelength range; the diffraction efficiency is simply the average efficiency of S and P polarization.
