Paper Abstract

Optical design requires an accurate knowledge of the dispersion functions for the materials in each lens. For systems to work over a wide range of temperature, knowing the temperature dependence of these functions is as important as knowing the coefficients of thermal expansion. The dispersion curves of several NRL-developed infrared glasses were measured over a temperature range that spanned, at minimum, -20°C to 60°C. Details concerning the data fidelity, data modeling, fit results, and physical implications of the results will be provided in this work.
