Manufacturer Description:
The D-652 Coordinate Autocollimator combines a 5 inch (127 mm) aperture with a 26 inch (660 mm) focal length optical system into an 18 inch (457 mm) long instrument. The short-coupled design and the midsection eyepiece make it possible for one operator, while viewing through the eyepiece, to adjust one or more mirrors without assistance.
