Suprema® ZeroDrift™ Thermally Compensated Mirror Mounts
Suprema® ZeroDrift™ Thermally Compensated Mirror Mounts
ZeroDrift™ optical mirror mounts feature patent-pending kinematic elements that compensate the mount for temperature-induced alignment drift. This innovation has resulted in an 85% improved optical pointing stability compared to other stainless steel mounts.
- Resistant to temperature-induced misalignment
- Reduces thermal drift by 85%
- OEM and low wavefront distortion versions See All Features

Features
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 patent-pending 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.
Locking Actuators
For long-term stability, Suprema® ZeroDrift™ Mirror Mounts feature lockable adjustment screws. The jam nut lock, used for SS100T, exerts an axial force on the adjustment screw which locks the mirror mount's alignment in place and can be tightened by hand. The lever lock, used for the ST05 models, and the flexure lock built with an AJS bushing, used for SU100TW, exert a tangential force on the screw to prevent rotation. Adjustment and locking actions for these models are accomplished using a single tool from the same side of the mount.
Front- and Rear-Loading Options
The Suprema® ZeroDrift™ Mirror Mounts are offered in both front- and rear-loading versions. Installing a mirror from the front is more convenient, which can be useful when replacing mirrors without having to disrupt an optical system setup or remove its components. Rear-loading a mirror guarantees that the reflective surface will be flat on the face of the mount irrespective of the mirror's thickness.
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.
