Product Family Description

  • 100 TPI Fine Adjustment Screws
  • Fingercuts for Convenience and Accuracy
  • Tip/Tilt Range:±5°

Our family of TECHSPEC® Kinematic Optical Mirror Mounts allows precise and accurate adjustment of optical components. Each mount features high accuracy adjustment screws in either two (2) or three (3) screw versions for control of tip and tilt. Three screw versions allow additional translation in the optical axis. Nylon-tipped locking screws (1.5mm hex key included) prevent damage to the optics, and incorporated fingercuts make placement of optical components convenient and accurate.

Construction materials ensure quality and repeatability. Stainless steel inserts are used for all adjustment screw contact surfaces and specially designed dampening grease provides smooth movement. Adjustment knobs are removable for Allen Key or motorized adjustment (2mm key size). Included hardware kit contains post-mounting screws and Allen wrenches for adjustment.

These mounts are designed to connect to our TECHSPEC® Metric Stainless Steel Mounting Posts. When the male-thread adapter is removed from the post, either an M4 or 8-32 tapped hole is available to accept the post-mounting screw from the mount.

TECHSPEC® Optical Mount Accessories available to easily integrate TECHSPEC® Kinematic Optical Mirror Mounts into a variety of application setups.
