Product Description
Transmission gratings are designed to direct as much light as possible for a specific wavelength into lower orders. Our plane transmission gratings are used in the visible spectrum. They can be used in spectrographs or as beamsplitters for monochromatic light sources, such as lasers. Geometrical optic considerations require relatively coarse groove spacing (usually, no more than 600 g/mm).

Shown here is an example of an efficiency curve for our plane ruled reflection gratings. A complete set of curves are available on our website. Note: Many of these curves are relative (not absolute). They are only representative, and can vary significantly depending on use geometry and measurement technique. Two masters with the same catalog number may have different efficiency curves.
