  • Optical gas concentration measurement apparatus
    Patent number: 11573174
    Abstract: An optical gas concentration measurement apparatus is disclosed. The optical gas concentration measurement apparatus includes a thermally insulated enclosure that has a gas sample cell situated within. A thermally-insulating, light-guiding element passes through an access port of the thermally insulated enclosure and is configured to direct light from a light source outside of the thermally insulated enclosure to the gas sample cell. A light detector outside of the thermally insulated enclosure is optically coupled to the gas sample cell and an electronic assembly outside of the thermally insulated enclosure is configured to receive information from the light detector.
    Type: Grant

  • Thermal imager with protective grid
    Patent number: 9006655
    Abstract: A protective enclosure for a thermal imager having a window and protective grid. The protective grid is designed in relation to the lens of the thermal imaging device such that the grid pattern geometry and size accommodate the thermal imaging device's pupil size.

  • Method and apparatus for electronically generating an outline indicating the size of an energy zone imaged onto the IR detector of a radiometer
    Patent number: 7339685
    Abstract: A radiometer includes a sighting system that generates a digital image of an object surface having an area that is to be imaged onto the IR detector. A shape outline is overlaid on the digital image of an object surface to indicate the extent of the energy zone that is imaged onto the IR detector. In one embodiment, a shape is displayed between the locations of two imaged skewed laser dots to indicate the extent of the energy zone without requiring a range determination.
