In traditional top adjust mounts, a screw pushes directly on a machined ramp to adjust the mirror position. To improve upon this design, our Stability™ top adjust mounts utilize a cam mechanism as a pivot in combination with sapphire kinematic bearing surfaces to maneuver the ramp and adjust mirror position, together with dual mounting holes and thick frames, resulting in very low friction and superior mechanical stability. These mounts are also designed with a unique three-point optic-retention system which optimizes stability while minimizing wavefront distortion.

With the axial 3-point mounting, because there are twice as many mounting points, the forces that would cause distortion are essentially cut in half, more distributed, and axially opposite to eliminate bending.

These mounts feature alignment pin holes (shown in red) on the bottom (base) of the mount to enable keying of the position and orientation by means of dowel pins when directly mounting. (Note: Dowel pins not included with mount.) This is especially helpful in OEM applications.
