Transmission Grating: T-1739-1035s-120x20-97

Transmission gratings operate to angularly disperse incident light into a spectrum. The LightSmyth product line of transmission gratings by II-VI 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 (97%) 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. 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.
