KM100 Mounted on FM90
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 8-32 (M4) tapped holes as well as one #8 counterbored hole for inserting a cap screw from the underside of the mount. 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.
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. These centering plates are designed to position the front face of an optic in the KM05(/M), KM100, or KM200 Kinematic Mount over the center of a Ø1/2" or Ø1" post. Centering the optical face reduces any off-axis shift of the optical path when rotating the mounting post.
The KCP1(/M) and KCP2(/M) are equipped with two 8-32 (M4) taps. Thread a Ø1/2" post into one end, and secure the kinematic mount to the centering plate using the other tap. Since our kinematic mounts for Ø1/2" optics are designed with an 8-32 (M4) tap instead of a #8 counterbore like their Ø1" and Ø2" counterparts, the centering plate [KCP2(/M)] for use with this mount provides one 8-32 (M4) tap and one #8 counterbore (see image to the right).

KMCP Centers Mirror Over the Rotation Axis
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.
