ABSTRACT:
A laser tube is rigidly mounted within a cylindrical metallic housing, and end rings are attached thereto. Each end ring has an opening for passage of the beam, and a plurality of radially disposed openings. Inside the housing, a smaller adjustment ring is provided, and outside the end rings are reference rings adapted to receive lenses, filters, or the like. Screws engage and penetrate the outer ring, pass freely through the end ring, and engage the inner ring. The outer and inner rings are movably adjustable relative to the housing axis and the laser beam, whereby optical apparatus attached to the outer ring may be positioned precisely relative to the laser beam.
