When it is necessary to mount two or more mirrors very close to each other these mounts provide the best solution. They are intended to be post or pedestal mounted so that the mirrors can be almost touching each other. The two adjusters are located to either side of the optical path where they do not interfere with the beam. Unclamped, the mirror can be rotated through a full 360 degrees about its surface. Once clamped fine movement is made by the micrometer adjusters over a range of ±5 degrees. The mirrors are attached by means of small nylon clamp screws which hold them into a thin ring so that there is very little mount hardware in the region of the mirror. The base of the mount has an 8-32 or M4 threaded hole for attachment to a post or pedestal base.
