Features

3-Point Axial Clamping Reduces Mounting Stress

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.

Test Results - Minimized Distortion

Interferometric testing results show the flatness of the mirrors held in these mounts, measure at 0.100 wave PV (peak to valley).   Compare this to mirrors held in a mount with a nylon-tipped set screw where the flatness degrades to 0.600 to 0.800 wave PV.  An unconstrained 1/10th wave mirror will typically measure 0.090 wave PV.

Many Actuators - One Mount

The ULTIMA's industry-standard clamp design allows many different types of actuators to be used to adjust the mirror position to meet the requirements for any application. Actuators can be replaced with ease by simply loosening two screws to allow the actuator to gently slide into and out of the mount. ULTIMA mounts are compatible not only with standard knob and hex-key adjustment screws, but also with micrometers and motorized actuators. See our Recommended Compatible Actuators in the Accessories section below.

Locking Adjustment Screws

For long-term stability, ULTIMA® Low Wavefront Distortion Mirror Mounts use a Flexure Lock built with an AJS bushing. Flexure Locks exert a tangential force on the screw to prevent rotation.
