Product Details

Concavegratings for flat-field spectrographs

Diffraction Gratings are optical components used to separate light into its component wavelengths, usually used in spectroscopy, or for integration into spectrophotometers or monochromators. Diffraction Gratings contain a series of closely packed groovesthathave been engraved or etched into the Grating’s surface. Diffraction Gratings can be either transmissive or reflective.
