Paper Abstract

The refractive index of an infrared transmitting glass, AMTIR-1, has been measured at infrared wavelengths and cryogenic temperatures. Experimental data are presented for wave-lengths of 7-12 micrometers (pm) and for temperatures of 170-350K. The change in index with temperature, dn/dT, was determined as well. An overall accuracy in index of five parts in the fourth decimal place was achieved. In addition to results, the equipment, measurement procedures, and error estimates are also described.
