The Thorlabs Polaris® XY Translation Mount is the ultimate solution for applications requiring stringent long-term alignment stability. The front plate features an SM1-threaded (1.035"-40) bore with a stainless steel retaining ring for mounting Ø1" lenses or SM1-threaded components. The translation plates are secured using a patent-pending flexure preloading mechanism that is lockable using a setscrew with a ball tip that introduces minimal angular shifts during locking and unlocking. This design provides high holding force and pointing stability while allowing quick and easy installation of the optic. Two mounting positions are possible for right- or left-handed orientations.
Optic Retention
This mount features an SM1-threaded bore which allows a variety of optical components to be secured. A stainless steel retaining ring is included with each mount; additional retaining rings can also be purchased separately. Polaris optic bores are precision machined to achieve a fit that will provide optimum positional stability over changing environmental conditions such as temperature changes, transportation shock, and vibration. The performance will be diminished if these mounts are used with optics that have an outer diameter tolerance greater than zero or smaller metric optic sizes (Ø25.0 mm). To order a mount designed for metric optics, please contact
Design
Machined from heat-treated stainless steel, Polaris mounts utilize precision-matched adjusters with ball contacts and sapphire seats to provide smooth kinematic adjustment. As shown on the Test Data tab, these mounts have undergone extensive testing to ensure high-quality performance. The Polaris design addresses all of the common causes of beam misalignment; please refer to the Design Features tab for detailed information.
Post Mounting
The POLARIS-1XY translation mount is equipped with #8 (M4) bores for post mounting, as well as Ø2 mm alignment pin holes around the mounting holes, allowing for precision alignments when paired with our posts for Polaris mirror mounts. See the Usage Tips tab for more recommendations about mounting configurations.
