Latest Patents

One of Comey's latest patents is the "Dark mirror coated prism." This invention features an improved prism cold shield designed for use in infrared detection systems. It includes a detector array made up of multiple detectors sensitive to specific radiation within a predetermined wavelength band. The prism consists of a substrate with a top surface partially coated with a first coating layer, which defines several bow-like stripes alternating with openings covered by a second coating layer. The bottom surface of the substrate is partially coated with a third coating layer, creating a line of windows aligned with the top surface openings to define a field of view for the detectors. The first and third coating layers are made of high absorption, low reflectivity materials, while the second layer serves as an anti-reflective coating.

Another significant patent is the "Tilted array with parallel cold shield." This invention provides a cold shield for an array of detectors of a predetermined shape. It features a first cover made of radiation-blocking material with parallel rows of apertures, positioned at a first distance from the detectors. A second cover, also made of radiation-blocking material, contains a plurality of apertures of the same predetermined shape and is located at a smaller distance from the detectors. This design minimizes background radiation while allowing desired radiation from various angles to reach the detectors.
