ABSTRACT:
A mounting adapter for coupling a TV lens or other type of lens to a night vision device is provided. The mounting adapter is a longitudinal tubular member that has an exterior surface that tapers from a wider first end to a narrower second end. The interior surface of the wider first end includes a first threaded region to removably couple the mounting adapter to a night vision device. A second threaded region is located on the interior surface of the narrower second end for removably coupling a TV lens or other optical device to the mounting adapter. The mounting adapter defines a cavity for receiving a portion of an image intensifier tube, this cavity being located just past the first threaded region. At the end of the cavity there is defined an annular-shaped seat which abuts against the image intensifier tube when the mounting adapter is coupled to the night vision device. A third threaded region for receiving an annular lens retainer is located between the annular-shaped seat and the second threaded region.
