Machined from heat-treated stainless steel, Polaris mounts utilize precision-matched adjusters with ball contacts and sapphire seats to provide smooth kinematic adjustment. To order a mount designed for metric optics, please contact Tech Support. These mounts are not designed to be used with optics that have an outer diameter tolerance greater than +0/-0.1 mm, such as metric mirror sizes (Ø12.5 mm, Ø25 mm, or Ø50 mm). Polaris optic bores are precision machined to achieve a fit that will provide optimum beam pointing stability performance over changing environmental conditions such as temperature changes, transportation shock, and vibration. These designs provide high holding force and pointing stability with minimal optic distortion. These Polaris mounts use either a monolithic flexure arm or a flexure spring and setscrew combination to hold the optic. Replacement piezoelectric adjusters for the mounts are also available separately below. We recommend driving the piezo actuators using our benchtop or Kinesis ® K-Cube™ piezo controllers. The Polaris ® Kinematic Mirror Mounts with Piezoelectric Adjusters are the ultimate solution for applications requiring stringent, actively monitored, long-term alignment stability.
