The HVM-1i Industrial Vertical Drive Kinematic Optical Mount is unlike any optical mount in its class. It's very stable and yet easy to adjust without burning your fingers. The HVM’s unique ball-and-wedge drive mechanism enhances the overall performance of the 1 inch (25.4mm) diameter optical mount by reducing stiction and backlash to negligible levels while maintaining a compact and robust package.

This unique drive mechanism also allows substantial angular tilt without adjustment screws protruding from the back of the mount, where fingers can block the beam. At a scant 0.75 inch thickness the HVM can be placed in optical systems requiring minimum footprint. Newport’s in-line spring mechanism provides targeted tension at appropriate points to ensure the HVM is stable both short-term and long-term.
