ABSTRACT:
An improved adaptor for coupling a video camera to an endoscope, borescope, or the like includes a focusing mechanism and an independent zoom or magnification variation adjustment mechanism. The zoom mechanism will move two lens groups along an optical path simultaneously, but at different speeds. Each lens groups preferably includes a pair of lenses affixed together as a doublet. By controlling the position of the doublets relative to a pair of focusing lenses, the present adaptor provides an optically compensated zoom mechanism which allows changes in the magnification of the adaptor throughout a wide magnification range without having to refocus the adaptor.
