### Diffraction Gratings - Ruled Gratings - Gratings | Edmund : Consulting inventory

Diffraction Gratings consist of a series of closely packed grooves that have been engraved or etched into the Grating's surface. Diffraction Gratings can be either transmissive or reflective. As light transmits through or reflects off a Grating, the grooves cause the light to diffract, dispersing the light into its component wavelengths.

### Diffraction grating - Wikipedia : Consulting inventory

In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.
