The HVM-20Mr is an Industrial Vertical Drive Kinematic Optical Mount specifically made for 20 mm optics. It has a compact, stable design for easy top adjustment away from the beam path. Optics can be rear-loaded, and secured with a set screw to ensure the front face of the optic is always in the same location regardless of its thickness. The mount has standard features such as a 20 mm optical axis height, 100 TPI locking actuators, and can fit 4mm – 6.35mm thick optics. The HVM-20Mr is designed with several mounting including #8 (M4) clearance holes for simple mounting via cap screws.
