UDT Model 1000 Autocollimator with Collimation Objective Tube,
This is a modular autocollimator assembly manufactured by United Detector Technology (UTD). It probably dates from the early 1980’s or late 1970’s. The model 1000 autocollimator head had two different focal length lenses available, as well as several types of detectors. There is a BNC cable coming from the collimation head, but there is no beam-splitting prism present. We are not sure if a detector is within the head, or if there was some sort of light source. If it were a detector we believe there would have been some sort of quadrature sensor, in which case one would need significantly more data lines than a simple coaxial connection. The end of the autocollimator tube is an open sleeve of 1 inch diameter.

Probably the more important element of this offering is the collimation objective tube. The outer diameter of the sleeve is 3.5 inches, and a flat has been milled on the bottom of the housing with 1/4-20 screw threads in three places. The focal length of the objective is 400mm, and the diameter is just shy of 2.75 inches. This is the larger of the two interchangeable objectives – the other had a focal length of 200mm.

There is a tiny chip out of the periphery of the lens that has been covered with an opaque epoxy, but the rest of the lens appears to be in perfect condition. (See last photo). It probably cuts down the effective aperture by less than 1/4 mm.

This Nikon measuring stage includes a clamping base that allows precise alignment of the X and Y axes. We are not sure what instrument it fits, but it was probably intended for use with their line of measuring microscopes or with some of the smaller profile projectors.

The stage has a range of motion of 1 by 1 inch with micrometer actuators. Spindles may be read directly to 0.0005 inches and to 0.0001 inches via verniers. The stage includes a graduated theta plate with two T-slots. The stage rotary motion is graduated in degrees and can be read to 2 minutes of arc via a vernier. There is a clamp for stage rotation.

Overall height of the stage is approximately 3 inches from the mounting plate reference surface. The mounting plate surface is better than 5 inches square. Overall diameter of the stage is approximately 7 inches. There is a clear bore of slightly less than 3 inches. The stage is missing the glass insert, which would have been 105mm in diameter. The stage weighs 13.75 pounds and is of massive construction.

All motions work very smoothly. The stage is in very fine condition. There is a bit of rust residue in the bottom plate but the ball-bearing ways are in perfect shape. Overall cosmetic condition is very fine.
