Diffraction gratings

Description

Diffraction gratings are dispersion devices that are made from glass etched with fine grooves, spaced at the same order of magnitude as the wavelength of the light to be dispersed, and then coated with aluminium to reflect the light to the photodiode array. Diffraction gratings reflect the light in different orders and filters need to be incorporated to prevent overlapping.
