Abstract
A mount for optical elements includes a frame and a holder for holding optical elements such as lenses and/or an image detecting element such as a CCD. The frame and holder are cylindrical. The diameter of an interior screw of the holder is smaller than the diameter of a mating exterior screw of the frame so that backlash between the frame and the holder at the screw connection is substantially eliminated as the frame is rotated relative to said holder to tighten the inner surface of the holder against the outer surface of the frame. In one embodiment, at least one notch extends in a longitudinal direction of the holder to assist in elastic deformation of the holder. In another embodiment, a tightening ring formed in a C-shape is mounted around the exterior surface the holder to constrain elastic deformation outwardly when the screw connection is tightened.
