Volume‐phase holographic (VPH) gratings show great potential as an alternative dispersing element to the classical surface‐relief (SR) gratings presently used in most astronomical spectrographs. We present an introduction to this technology and give the results of an evaluation of three different VPH gratings: a 300 line mm−1 grating optimized at 1064 nm, a 1200 line mm−1 grating optimized at 532 nm, and a 2400 line mm−1 grating optimized for operation at 532 nm.
