  • METHOD OF CONTROLLING STRAY LIGHT REFLECTIONS IN AN OPTICAL SYSTEM
    Publication number: 20180039041
    Abstract: A method of fabricating an optical housing includes forming a pattern comprising a predetermined surface feature on an interior surface of the optical housing. The predetermined surface feature is configured to control reflections of stray light along an optical path between an aperture at a proximal end of the optical housing and a detector at a distal end of the optical housing.

  • Method and system for controlling stray light reflections in an optical system
    Patent number: 9823544
    Abstract: Systems and methods for controlling stray light reflections are provided. An optical system includes an aperture having an optical axis passing therethrough, one or more optical elements disposed along an optical path, and a detector disposed along the optical path. The system further includes an optical housing disposed between the aperture and the detector. The interior surface of the optical housing includes a predetermined surface feature adapted to control reflections of stray light along the optical path between the aperture and the detector.
