- 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 center of the nut translates between 0.46" (11.7 mm) and 0.79" (20.1 mm) from the center of the counterbored #8 (M4) hole used to post mount the centering plate. The mirror's front surface can 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 #8 (M4) Through Holes
Use an 8-32 (M4) caphead screw to attach the mount to the KMCP using the sliding nut. The counterbored #8 (M4) through hole on the KMCP is then used to attach the KMCP to a post.
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.
