90-Degree Image Rotator with Manual Positioning

Description

This assembly was manufactured by Optical Specialties as a part of one of their measurement systems. It appears to be an image rotation system consisting of two separate motions. The upper portion of the mount revolves through an angle of about 90 degrees and is manually adjusted and clamped via a large knurled knob.

The lower portion of the system is electronically actuated (we have the cable but not the electronics) and appears to rotate a dove prism type assembly through an angle of 45 degrees which results in an image translation of 90 degrees. Rotation is not continuous, rather there are a pair of retro-reflector systems located in the periphery of the housing.

Seemingly, the user would adjust the camera or detector to one axis of a geometry using the manual setting, and then be able to switch rapidly between that position and a second position oriented 90 degrees away. Looking at the base of the system (third photo), the central portion within the chrome bearing is that part that rotates. The top mounting remains stationary.

This system was installed on the modified Nikon trinocular tube we have listed elsewhere. The upper portion has three set screws for securing the detector – it is not threaded.
