Hide Overview

OVERVIEW

This page features Thorlabs' 6-axis kinematic optic mount and prism mounting accessories. The K6X 6-axis kinematic optic mount is designed as a general purpose, high precision positioner and features an SM1 (1.035"-40) threaded bore for mounting Ø1" optics. The K6A1 (K6A1/M) prism mounting attachment is designed to provide a 0.5" x 1.44" platform mounted to the rotation stage of the K6X. More details for each product are given below.

K6X Rear View
The K6X Features X-Y Translators and Kinematic Pitch/Yaw Adjusters (Click to Enlarge)
  • Compact 6-Axis Optic Mount
  • Kinematic Pitch/Yaw Control: ±4° with Adjustment per Revolution of 5 mrad/rev
  • X and Y Translation: ±1.5 mm*
  • Continuous 360° Roll Control
  • Maximum Optic Thickness: 0.37" (9.4 mm)
  • SM1 Threaded Bore for Ø1" Optics
  • #8 (M4) Counterbore Allows for Imperial and Metric Mounting
  • 30 mm Cage System Compatible

The K6X 6-axis kinematic optic mount is designed as a general-purpose, high-precision positioner. Applications include crystal alignment, lens alignment for diffraction limited performance, and fiber optic coupling. The K6X is SM1 (1.035"-40) threaded to accept Ø1" optics and our Ø1" Lens Tubes. 4-40 tapped holes on the back surface are designed for attaching a 30 mm Cage System assembly.

*Please note that adjustment in the X- or Y-axis will rotate the optic (~2°). If your application is sensitive to the rotational alignment of the mounted optic, you will need to utilize the rotational adjustment of the K6X after the X- and Y-axis adjustments are made. Z-axis translation requires the use of three adjusters (pitch, yaw and pivot). Also note that the rotational adjustment cannot be locked in position.

Hide Prism Mounting Attachment

Prism Mounting Attachment

  • Mounts on the Face of the Rotation Ring
  • 0.5" x 1.4" Platform
  • 1/4" (6 mm) Adjustment Range

The K6A1 (K6A1/M) is a 0.5" x 1.44" platform designed to be mounted on the rotation ring on the K6X 6-axis kinematic mount and the CRM series of 30 mm cage compatible rotation mounts. The platform is mounted using the included #4-40 screws (hex key included). The platform has an adjustment range of 1/4" (6 mm) so that the optic placed on the platform can be positioned on the axis of rotation. The platform has four #6-32 (M4) tapped holes on the corners that can be used to mount, among other things, the included PM3 (PM3/M) prism clamping arm.

Hide Clamping Arms

Clamping Arms

  • Provides Clamping Force for Our Mounts
  • Stackable 6-32 (M4) Threads on Top and Bottom of Post
  • PM3(/M): Holds Optics up to 0.97" (24.6 mm) Tall
  • PM4(/M): Holds Optics up to 1.61" (40.9 mm) Tall

Thorlabs' PM3(/M) and PM4(/M) Clamping Arms use a nylon-tipped setscrew to secure objects in our mounts and V-clamps. The PM3(/M) provides vertical travel of up to 0.97" (24.6 mm) and features a 0.69" (17.5 mm) long clamping arm. In contrast, the PM4(/M) provides vertical travel of up to 1.61" (40.9 mm) and features a 1.16" (29.3 mm) long clamping arm.

The clamping arm is held to the post using a flexure mechanism that locks with a 5/64" (2 mm) balldriver or hex key. The post includes a Ø0.09" (Ø2.3 mm) through hole that provides added torque when tightening down the post.

The PM3(/M) clamping arm can be used to hold 1" (25.4 mm) tall optics with the addition of a second post. Without the second post, the top surface of the clamping arm will be positioned above the top of the post, causing less-than-full engagement of the flexure mechanism.
