A focusing, collimating, and beamsplitting test system for testing laser rangefinders for their beam quality, ranging accuracy, and sight unit alignment. The system includes holographic optical elements in place of conventional mirrors, lenses and beamsplitters. The advantages of this system are that it not only reduces the size and weight of optical elements, but also reduces the number of required elements. Consequently, the resulting test equipment requires less labor to assemble and is more compact and much lighter than conventional test systems.

Apparatus for testing alignment of a first optical path with a second optical path, said apparatus comprising: a detector responsive to incident energy of a first wavelength or wavelength range; a test object for reflecting visible wavelength energy; and holographic optical means for: (a) receiving said visible wavelength energy from said test object, collimating said energy and directing said energy along a first optical path; and (b) receiving energy of said first wavelength or wavelength range from along a second optical path; said test object and said detector being cooperatively placed such that if said second optical path is properly aligned with said first optical path said holographic optical means will focus and direct said energy of said first wavelength or wavelength range onto said detector.
