We have developed a compact, computer-piloted, high sensitivity broadband imaging system for laboratory research that is compatible with various detectors. Mirror optics allow application from the visible to the far infrared spectral range. A prototype tested in conjunction with a mercury cadmium telluride detector exhibits a peak detectivity of 6.7×1010 cm Hz1/2/W at a wavelength of 11.8 μm. Temperature and spatial resolutions of 0.06 K and 1.6 mrad, respectively, were demonstrated.
