Product Description
This is a very unusual component mount. It is very massive (over 10 pounds) and machined from solid aluminum. The block is 6 inches square and 3.5 inches tall. All of the threaded mounting holes appear to be metric. Both the base and the top (not sure which is which) have a 125mm square bolt hole pattern threaded for M6 hardware. Centered on the thinner face is a recessed 25mm x 0.75 threaded ring. On the opposite face is a 45 degree recess for mounting a beam-splitter. There is a cross bore in the larger part of the base which is centered to the optic axis of the beam-splitter.
About the periphery of the mount are several micro-threaded adjustment screws (hex head). These are able to adjust both the leveling and very slightly, the rotation of one part with respect to the other. The threaded ring, although centered within the thinner plate, is actually a part of the main portion of the mount - the only portion that moves is the thinner mounting plate.
This appears to be a custom system but would certainly be useful in a number of optical breadboard setups where extremely fine adjustments have to be accomplished for particularly heavy systems.
