Abstract:
1. An image acquisition device for use in an environment, comprising A. an enclosure, B. an image capture medium disposed within the enclosure, C. a lens sub-assembly that is disposed within the enclosure, the lens sub-assembly including a lens that focuses light on the image capture medium, D. a window sub-assembly that is moveably coupled to the enclosure, the window sub assembly including a window that admits the light into the enclosure for capture by the image capture medium while protecting the lens or at least one component within the enclosure from the environment, E. a seal that is disposed between, and in contact with, the window sub-assembly and the lens sub-assembly, such that rotation of the window sub-assembly translates to the lens sub-assembly, the seal preventing at least selected contamination from the environment from entering into the enclosure or vice versa while providing at least temporary fixation of the lens focus by means of a friction fit at the seal, wherein the window subassembly is arranged such that movement of the window subassembly effects focusing of the light by the lens on the image capture medium.
