We interfaced SOFAST with a temperature chamber at CFV Labs in Albuquerque, New Mexico. This enabled us to vary mirror temperature to commanded values, and measure the change in optical shape as a function of temperature. Some mirrors show significant sensitivity to temperature variation, such as the example shown here.
