Abstract:

In a lens assembly and housing therefor for use in conjunction with an optical apparatus, the lens assembly includes a lens frame of nonferrous material and defining a window having a lip therein along a periphery of the window, a lens disposed in the window and adjacent the lip, a pair of spaced magnets on the frame, and a grip formed on the frame. The housing includes first and second walls opposed to each other and in part defining a pocket, the first wall being nonferrous and the second wall being magnetically permeable, the pocket being adapted to receive the lens assembly with the grip of the frame extending beyond the pocket. The magnets interact with the magnetically permeable second wall of the pocket to releasably retain the lens assembly in the lens assembly housing.
