Torrent Photonics Transmissive Gratings Description：

Transmissive gratings are a type of diffractive grating designed to diffract light transmitted through them at angles depending on wavelength. They have lower alignment sensitivities when compared to reflectance gratings, making them more robust given slight changes in environment.

Additionally, transmissive gratings have a significant edge on throughput when compared to traditional reflective gratings, and with our ability to use a fused silica substrate, we're able to achieve deep UV sensitivities.

See our specifications table for some typical diffraction efficiency curves optimized across wavelengths. The grating profiles can be modulated to optimize diffraction efficiency at certain wavelengths.
