This UDT 1010 Electronic Autocollimator came from a working environment but has not been tested.
From manufacturer website: UDT Instruments electronic autocollimators are compact optical instruments designed for measuring the angular position of reference surfaces. They are used wherever flatness, angle, or parallelism must be measured very accurately. Applications include automatic mirror alignment and servo control; quality control and testing of surface plates, machine surfaces and optical components; vibration and stability measurements, and structural flexure measurements.
The autocollimator requires a display unit Optical Position Indicator which must be sourced separately.
