ABSTRACT:
An improved prism cold shield for use in an infrared detection system which includes a detector array comprised of a plurality of detectors sensitive to a radiation of interest in a predetermined wavelength band. The prism comprises a substrate having a top surface partially coated with a first coating layer arranged to define a plurality of bow-like stripes alternating with top surface openings which are covered by a second coating layer. The substrate has a bottom surface partially coated with a third coating layer in a pattern to define a line of windows on the bottom surface which are aligned with the top surface openings so as to define a field of view for the plurality of detectors. The first and third coating layers ae comprised of high absorption, low reflectivity coatings in the wavelength band of the radiation of interest and the second coating layer is an anti-reflective coating.
