Product Family Description

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

TECHSPEC® Kinematic Optical Mirror Mounts allow precise and accurate adjustment of optical components in a wide range of applications. Each mount features high-accuracy adjustment screws, in either two-screw or three-screw versions, for control of tip and tilt. The three-screw versions specifically allow for additional translation in the optical axis. TECHSPEC® Kinematic Optical Mirror Mounts contain nylon-tipped locking screws (1.5mm hex key included) that prevent damage to the optics and incorporate finger cuts to make the 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 are available to easily integrate TECHSPEC® Kinematic Optical Mirror Mounts into a variety of application setups.
