Thermal expansion and other physical properties of the newer infrared-transmitting optical materials
1Department of Physics and Astronomy,University of Florida, Gainesville, Florida 32601, USA.
Abstract:
Values are given of the linear coefficient of thermal expansion for several of the newer ir-transmitting optical materials, as determined in the authors' laboratory. The materials include the six Irtrans (hot-pressed compacts), T-12, three single-crystal materials (magnesium fluoride, silver bromide, and cadmium fluoride), and two nonoxide glasses. Additional physical properties of these materials and of some of the older ir-transmitting materials are given in a large table for purposes of ready reference and comparison.
