UV Transmission Gratings 、Visible Transmission Gratings、NIR Transmission Gratings Various wavebands available for gratings.

Transmission gratings have specialized uses in spectrometry. Any optical imaging system, such as a camera or telescope, can be converted into a spectrograph by placing a transmission grating in the system, typically in front of the objective lens. Transmission gratings also serve as convenient beamsplitters for monochromatic light sources such as lasers.
