ABSTRACT:
A dual laser beam angular separation control apparatus has a pair of rotatable mirrored flats that minimize the angular separation of two converging beams such that the beam crossing aperture is also minimized and remains fixed at a specific point. The apparatus further minimizes the optical path length that is required to cause two parallel laser input beams to be converged to a minimum aperature size at crossing without the use of lens, etc.
