The HVM-05i Vertical-Drive Industrial Mirror Mount is unlike any optical mount in its class. Its body is made entirely from stainless steel, allowing it to be exceptionally stable and compact. It is only 0.31 in.(8 mm) thick. The HVM-05i is adjusted with two top-accessible 80-TPI screws having 1/16-in (1.5 mm) hex keys. Each adjuster is labeled with the axis it moves; either P for pitch (elevation) or Y for yaw (azimuth). Designed for OEM applications, the HVM-05i can be mounted with any or all of three clearance holes located in the rear of the mount and has an additional 1/16-in. alignment pin hole on the base for keying the mounting position.
