a laboratory device for testing optical instruments and parts thereof. In an optical bench, sliding supports, or carriages, slide along a heavy track. They carry various stands and tables on which the instruments or parts being tested are mounted. The carriages can be displaced along the bench’s track and securely fastened at any point. The mechanical displacements are exactly parallel to the optical and sighting axes of the instruments mounted on the optical bench. An optical bench can have a length of up to several meters.
