Abstract
Collaboration between Kaiser Optical Systems, Inc. and the Department of Physics and Astronomy at Johns Hopkins University has resulted in the construction of volume phase holographic (VPH) transmission gratings that were subsequently tested in a cryogenic environment. VPH gratings were built on two popular optical glasses and subjected to temperatures near 100 Kelvin. Test conditions, observations and results are reported. Design considerations for optimizing VPH grating performance in cold environment is discussed.
