  • Multi-spectral uncooled microbolometer detectors
    Patent number: 7491938
    Abstract: A process and system for a medium wave infrared (MWIR) uncooled microbolometer focal plane array (FPA). One embodiment is for a single MWIR band uncooled IR detector, wherein the design and fabrication utilizes standard silicon processing techniques reducing manufacturing costs and preserving existing manufacturing capabilities. Another embodiment is a two color uncooled microbolometer IR detector providing broadband detection.
    Type: Grant

  • Short wavelength pass filter having a metal mesh on a semiconducting substrate
    Patent number: 4871220
    Abstract: A short pass filter is disclosed which exhibits high transmission in the infrared and/or visible region of the electromagnetic spectrum and which has high rejection in the microwave portion of the spectrum. The filter generally consists of a substrate of semiconducting material, for example, n-type germanium which has been doped with a suitable dopant or grown with impurities to provide a substrate with a known conductivity. A metal mesh is placed either on one or on both surfaces of the substrate, or is buried within the substrate. The combination of the semiconducting material and metal mesh produce a filter which will transmit infrared and/or visible radiation while rejecting microwave radiation through absorption and reflection.
