Description
Reflective ruled diffraction grating is a kind of optical glass substrate composed of dense, equidistant parallel lines, and the surface is coated with aluminized, multi-layer dielectric or other reflective film, which can separate white light into various components through diffraction effect or combine several different spectral beams into one(spectral beam combining-SBC grating).
