The 2.25-in. Microgage laser system consists of a laser transmitter and receiver that adapts to traditional optical alignment devices and that fits into standard optical hardware mounts. Developed by Pinpoint Laser Systems, the battery-operated laser is machined to the exact dimensional specifications of the optical telescope, and the receiver replaces the scribed ruler that is used in traditional alignment systems. The receiver can make measurements with sensitivity of 0.0001 in. and over distances from 12 in. to 80 ft. The attached display can be connected to a PC or laptop for recording readings and gathering data.
