Abstract
The rate of temperature change of an infrared detector produced by a cooling source in a typical Joule-Thomson cryostat (or other cooling device such as closed cycle cooler) is reduced by interposing a thermal filter between the detector and cooling source. The thermal filter comprises at least two layers of a first material having a good heat conductivity and high heat capacity, such as copper, separated by a layer of a second material having a high thermal resistance, such as an adhesive, e.g., a silicone rubber. The thermal filter of the invention is a thermal analog of an electrical filter which smooths out voltage or current oscillations.
