Abstract
An optical assembly includes a first tubular member having a pitched bearing surface proximate one end; a second tubular member having a pitched bearing surface proximate one end; a coupling tubular member fixedly coupled to the second tubular member and rotatably and slideably coupled to the first tubular member; and an optical element received in at least one of the first, the second or the coupling tubular members. At least a portion of the pitched bearing surface of the first tubular member is in engaging contact with at least a portion of the pitched bearing surface of the second tubular member. Rotating the first tubular member with respect to the second tubular member smoothly varies a distance between the first and second tubular members and allows a large, smooth adjustment with little effort. Rotation in a single direction returns the distances to an initial starting point.
