Abstract
A cooling apparatus for an infrared up-convertor incorporates a transparent heat sink in a conductive heat exchange relationship with a surface of the up-convertor and a Joule-Thomson effect cryostat located outside of the incoming and emitted image paths for cooling the heat sink. In this manner, the cooling apparatus does not obscure the path of the image to or from the up-convertor.
