  • Patent number: 9310668
    Abstract: Techniques and structures to facilitate efficient replacement of windows/domes of optical systems, such as turreted pointer/tracker systems and seekers and other such gimbal-based or fixed targeting systems. The techniques can be implemented, for example, in a mounting ring or bezel, wherein the dome/window center of curvature is actively aligned during assembly to a reference feature on a mounting bezel during the dome-to-bezel alignment. This reference feature then mechanically registers the dome-bezel assembly to a given chassis. In some embodiments, the techniques allow for positioning of a replacement window/dome on an optical lens system, such that co-boresight of multiple beam paths is automatically maintained.
