Features

• Positions Optical Face in Line with Post Rotation Axis
• 8-32 (M4) Nut Attaches Kinematic Mounts
• Positioning Range of 0.33" (8.4 mm)
• Compatible with any KM-Series Mount and all Ø1/2" Posts

As most conventional mirror mounts utilize their back plates for mounting to a post, the front surface of the optic is typically offset from the center of the mounting post. The KMCP Centering Plate utilizes an 8-32 (M4) nut embedded within a slotted counterbore to attach a kinematic mirror mount. The mirror's front surface can then be positioned over a range of 0.33" (8.4 mm), allowing the front surface of the mirror to be centered over the Ø1/2" mounting post. This reduces any off-axis shift of the optical path when rotating the mounting post. The KMCP can alternatively be used as an extension to insert a mount into a beam path when space limitations prevent using a post holder.

For a one-piece kinematic mount which centers the front surface of an optic over either a Ø1/2" or Ø1" post, please see our KM100CP kinematic mount with a post-centered front plate.

Mounts with Tapped 8-32 (M4) Holes

Use an 8-32 (M4) caphead screw to attach the mount to the KMCP using the counterbored #8 (M4) through hole on the KMCP. The sliding nut is then used to attach the KMCP to a post.

Features

• Rotates 90° to Clear Beam Path
• Kinematic Design Ensures Repeatability
• Post Mountable via 8-32 (M4) Tapped Hole

The FM90 is ideal for applications that require laser beams to be redirected for either diagnostic or beam sharing purposes. The hinged design allows an optical mount to be repositioned outside the beam path, and, when required, a simple flip of the mount relocates it back into its original position with a repeatability of 20 µrad.

The top surface of the mount is equipped with three #8 (M4) mounting holes as well as one counterbored 8-32 hole for fastening from the underside with a cap screw. The base of the mount is counterbored for a 1/4" (M6) cap screw to attach the mount to a post or an optical table.
