Features

  • Flip Mount Adapter and Adjustable Flip Platform Reposition Optic Mounts Out of a Beam Path
  • Fixed Centering Plates Align the Front Face of an Optic Held in a Standard KM05(/M), KM100, or KM200 Kinematic Mount Over the Post Axis
  • Variable Centering Plate Aligns the Front Face of an Optic Held in a KM-Series Mount or KS1 Precision Mount Over the Post Axis
  • Fabricated from Black Anodized Aluminum

These kinematic/gimbal mount accessories are ideal for adding flexibility to an optical setup. The FM90(/M) Flip Mount Adapter is offered for repositioning an optical mount at 90° from its original position. The FP90(/M) Adjustable Flip Platform features a similar design, but with an array of 8-32 (M4) tapped holes for mounting a variety of components. The fixed centering adapters are designed to align the front face of an optic held in our KM05(/M), KM100, or KM200 Kinematic Mount over the center of a Ø1/2" or Ø1" post. Thorlabs also offers a variable centering plate for translating a kinematic mount between 0.46" (11.7 mm) and 0.79" (20.1 mm) from the center of the #8 (M4) counterbored hole used to post mount the plate.

Dear Madam or sir, Do you know if the KCP05/M is compatible with the KM05FL/M or the FR Thanks in advance Best regards Olivier Blanc

Response from Chris at Thorlabs: The KM05FL/M in the nominal position seats the face of the optic off of the mounting hole 11.5mm. The KCP05/M would work best for a mount which does this at 13.3mm, which is what the KM05/M with a 6mm thick optic does. I'd recommend using the KMCP/M which can have a varied offset anywhere between 9-20mm if you are looking to have the optic face right over the center of post.

Flip Mount Adapter

FM90 Position Repeatability Test

Position Repeatability of the FM90 Flip Mount Adapter Over 20 Trials
  • 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 adapter into its closed position (as shown to the left) relocates the mount back into the beam path. As shown in the plot to the right, this can be accomplished with a repeatability of 20 µrad. In these tests a beam was redirected into a position detector using the FM90 Flip Mount and a KM100 Mirror Mount, as shown in the image to the right. The X-axis deviation, resulting from the tilt of the assembly, and the Y-axis deviation, resulting from the tip of the assembly, were each recorded over 20 tests.

The top surface of the adapter 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 adapter. The base of the adapter is counterbored for a 1/4" (M6) cap screw to attach the adapter to a post or an optical table.

Adjustable Flip Platform


Click to Enlarge

The flip platform makes it easy to add and remove components in a setup without having to reposition them on the optical table.
  • Designed for 90° Angular Adjustment
  • Up to 180° Adjustment Range in Certain Configurations
  • Side-Located Locking Cap Screw with 3/16" (5 mm) Hex
  • 1.25" x 1.25" Mounting Platform with Eleven 8-32 (M4) Tapped Holes
  • 8-32 (M4) Mounting Tap on the Side of Each Plate
  • Four 8-32 Tapped Holes on the Bottom Plate for Additional Mounting Options
  • Engraved Tick Marks in 15° Increments

The Adjustable Flip Platform is designed to attach to the top of our Ø1/2" or Ø1" posts and provide flexible mounting options for components. The flip platform can be secured on the post using the #8 (M4) counterbore located in the center of the bottom plate, or the 8-32 (M4) tapped mounting hole on the side of each of the two plates. The 1.25" x 1.25" top plate features eleven 8-32 (M4) tapped holes for mounting components.

The angle of the top plate can be adjusted between 0° and 90° with respect to the optical table surface when mounted using the counterbore in the center of the bottom plate. When mounted using the 8-32 tapped hole on the side, the top plate can be adjusted between -90° and +90° with respect to the optical table surface. In order to lock the platform in place, tighten the cap screw on the side using a 3/16" (5 mm) balldriver or hex key.

The flip platform can be converted between a right- and left-handed setup. Simply remove the locking screw, separate the top and bottom plates, flip the bottom plate upside-down, and reassemble the flip platform. This allows the user to choose the direction from which the locking screw is accessed, in case one orientation better suits the experimental setup.

Fixed Centering Plates for Kinematic Mounts

KCP05 Centering Plate Application
Click to Enlarge
KM05 Being Connected to the KCP05 Centering Plate
  • Centers Mirror Face Over Post Rotation Axis for KM05(/M), KM100, or KM200 Standard Kinematic Mount
  • Constructed from a Single Piece of Black Anodized Aluminum

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
  • Positions Optical Face in Line with Post Rotation Axis
  • 8-32 (M4) Nut Attaches Kinematic Mounts
  • Positioning Range of 0.33" (8.4 mm)

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.

This centering plate is compatible with any KM-series mounts, the KS1 Precision Kinematic Mount, and all Ø1/2" Posts.

Kinematic Mounts with #8 (M4) Through Holes for Mounting Kinematic Mounts with Tapped 8-32 (M4) Mounting 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. 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.
