This is a two-axis gimbal-type mirror / lens mount marketed by Coherent Optics, Model Number 58. The mounting is quite clever � the turning axes are cylindrical magnets that also act as bearings. Two Starrett micrometer spindles actuate the motions. They bear against additional magnetic pads. I am not sure how repetitive the positioning is but there doesn�t seem to be much play at all in the bores for the magnet bearings.
The mirror mount will accept mirrors up to 2� in diameter, and using the clamping ring supplied, between 0.350� and 0.700� thick if the ring is not to be set proud of the mounting face. Clear aperture of the mount is 1.875�. Aperture is reduced by the clamping ring to 1.750�. Tilting range of both axes easily exceeds plus or minus 6 degrees.
The mounting base is 3.875� by 2.000� wide and has two counterbores for � 20 cap screws 2� apart, centered on the optic axis of the mount. The optic axis is located 1.375� from the end of the mounting plate.
The mount is in extremely fine condition.
