Abstract

Multilayer optical absorber coatings may be applied to the faces of thermal detectors to enhance their sensitivity at wavelengths at which the detector2material exhibits low absorptivity. These coatings have extremely low mass (<100 pg/cm ) and the absorptance may be varied from 0 to near 100%. The design of these coatings is discussed, based on considerations derived from the detector application and experimental data is presented showing the effect on sensitivity.
