Volume Phase Holographic (VPH) Gratings in Astronomy

Volume phase holographic gratings are now being used extensively in astronomy because of their high diffraction efficiencies. VPH gratings are generally used in transmission. The diffraction is caused by a near-sinusoidal variation in refractive index perpendicular to the fringes (300-6000 lines/mm). For astronomy gratings, the active layer is typically 3-10 microns thick, which is sandwiched between glass substrates of a few millimetres in thickness. Prisms can be attached to reduce beam deviation (VPH grisms).
