Abstract
A light emission microscope includes a low temperature detector array which receives light through a room temperature projection optics system from a device under test. A cold aperture including a movable cold stop and a cryogenic filter absorbs unwanted thermal radiation emitted by the optics system. In one embodiment, a high resolution CCD camera can be used with the low temperature detector array and camera with a computer-controlled mirror providing emitted light to both cameras.
