SU100TW-F2K Mirror Mount

The SU100TW-F2K Mirror Mount features a combination of ZeroDrift™ thermal drift compensation and low wavefront distortion mirror mounting. Because the thermal deflection of optical mounts can be characterized, and these deflections can controlled through thermal expansion compensation, the thermal deflection of an optical mount can be nearly eliminated. This patented innovation is called ZeroDrift™ Technology. Specially designed ZeroDrift™ kinematic elements improve optical pointing stability by 85% compared to other stainless steel mounts. After a thermal fluctuation, most high-performance mirror mounts, while they return to their original alignment within a few microradians, but experience significant misalignment at elevated temperatures.

What is Thermal Drift Compensation?

Because the thermal deflection of optical mounts can be characterized, and these deflections can be controlled through thermal expansion compensation, the thermal deflection of an optical mount can be nearly eliminated. This patented innovation is called ZeroDrift™ Technology.

How Much does ZeroDrift™ Technology Reduce Drift?

Our tests show that ZeroDrift™ technology reduced the thermal drift of a stainless steel mirror mount by 85%. The graph shows thermal drift of 6 µrad and shift of 1 µrad.

Reduced Mounting Stress

ZeroDrift technology has been combined with our low wavefront distortion (LWD) retainer to hold mirrors in a way that will not induce optical distortion. It uses an axial three-point mounting method to gently, but securely, hold optics with tight flatness tolerances.

3-Point Axial Clamping Reduces Mounting Stress

Suprema^® ZeroDrift™ Mirror Mounts offer two types of front loading versions. The standard front loading version uses a set screw to secure the optic while the retaining plate featured in SU100TW-F2K uses 3-point axial clamping for securing the optic which reduces mounting stress.
