Detailed Description

A diffraction grating is a glass substrate carrying a layer of deposited aluminum that has been pressure-ruled with a large number of fine equidistant grooves, using a diamond edge as a tool. Light falling on such a grating is dispersed into a series of spectra on both sides of the incident beam, the angular dispersion being inversely proportional to the line spacing. We could manufacture various Diffraction Gratings, such as Original Diffraction Gratings and Replicated Diffraction Gratings.
