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.

Rooted in Kinematic Design

The design of ZeroDrift™ mounts still follows kinematic principals to ensure the highest stability and precision adjustment.  Each degree of freedom is constrained just once using the Cone, V, and Flat configuration.

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.

Locked-Down and Secure

All ZeroDrift mounts have a locking screws to enhance long term stability and discourage unwanted adjustment.
