  • Method and assembly for gas detection via a convergent birefringent filter
    Patent number: 6576905
    Abstract: An assembly and method provide sensitive high speed spectroscopic gas detection via the use of a non-collimated convergent light path through a birefringent crystal in a birefringent filter design to allow improved light collection and a reduction in the number of optical elements required to produce a useful absorption signal for the detection of gases.
    Type: Grant
    Filed: June 14, 2001
    Date of Patent: June 10, 2003
    Assignee: Gas Research Institute
    Inventors: Harold S. Lessure, Richard A. Evans, Richard P. Kunkle, Dale M. Matuza
