Transmission Grating: T-1000-1030-20X10-NOAR

Transmission gratings operate to angularly disperse incident light into a spectrum. The LightSmyth product line of transmission gratings by Coherent utilizes state-of-the-art design and precise lithographic wafer-scale fabrication to deliver record-breaking optical performance combined with low cost, providing your optical systems with a powerful competitive edge. These gratings offer excellent combination of highest diffraction efficiency, low PDL, and highly competitive pricing.

High diffraction efficiency (94% typical) allows our customers to minimize optical losses in multipass configurations. High-energy pulsed and CW laser systems will benefit from the high optical damage threshold of our diffraction gratings. This product is offered without an AR coating on the back (Non-grating) side. They contain no organic materials and can withstand temperatures of up to 500°C with no performance degradation.

Unlike reflection diffraction gratings, transmission diffraction gratings may be polarization-independent and can operate at the optimal Littrow angle with conveniently large angular separation between the input and diffracted beam.
