Features

  • Combines Kinematic Angular Adjustment with Rotation in One Mount
  • 1/4"-80 Lockable Adjusters Provide ±4° of Angular Adjustment
  • Engraved Rotation Scale with 2° Graduations Provides 360° Rotation
  • Fabricated from Black Anodized Aluminum
  • Compatible with SM05 (0.535"-40), SM1 (1.035"-40), or SM2 (2.035"-40) Lens Tubes

Thorlabs' Kinematic Rotation Mounts combine the features of our Precision Kinematic Mirror Mounts and Manual Rotation Mounts, providing continuous 360° rotational adjustment and ±4° kinematic tip/tilt adjustment. These mounts are therefore ideal for holding optics with rotational asymmetry, such as polarization optics or round cylindrical lenses.

The mounts are available in three sizes for directly mounting Ø1/2", Ø1" or Ø2" optics and are internally SM threaded for compatibility with SM05, SM1, or SM2 lens tubes. For direct mounting, one SM-threaded retaining ring is included. The rotation of the mount and position of the kinematic adjusters may be independently locked in position with locking screws. 

If higher adjustment resolution or control is desired, the 1/4"-80 adjusters used in these mounts can be switched with DAS110 or DM22 Differential Adjusters.

What is the distance between the center of optics and the bottom of the mount?
nbayconich  (posted 2017-12-08 02:49:10.0)
Thank you for contacting Thorlabs. The height from the center of your optic and the base of the KS1RS is 39.6mm. These dimensions can be found under the Auto CAD .pdf files in the product documents.

May I suggest this product but with precision rotary control?

Hello, thank you for contacting Thorlabs. I have posted this in our internal engineering forum, but I will also reach out to you directly about using multiple stock components together to achieve a similar performance.

Rotation Mount and Stage Selection Guide

Thorlabs offers a wide variety of manual and motorized rotation mounts and stages. Rotation mounts are designed with an inner bore to mount a Ø1/2", Ø1", or Ø2" optic, while rotation stages are designed with mounting taps to attach a variety of components or systems. Motorized options are powered by a DC Servo motor, 2 phase stepper motor, or an Elliptec™ resonant piezo motor. Each offers 360° of continuous rotation.

Ø1/2" Kinematic Rotation Mount

  • Three 1/4"-80 Lockable Stainless Steel Adjusters with Removable Knobs and Brass Bushings for Smooth Adjustments
  • Two #8 (M4) Counterbored Mounting Holes Allow Left-Handed or Right-Handed Orientations
  • SM05-Threaded (0.535"-40) Rotation Ring with Locking Screw

The KS05RS is designed to hold Ø1/2" (12.7 mm) optics in situations where it is necessary to control the tip/tilt position as well as the rotation of the optic. This mount is ideal for polarization optics such as linear polarizers or wave plates. The KS05RS features an SM05-threaded bore capable of mounting Ø1/2" optics up to 0.41" (10.4 mm) thick using the included SM05RR retaining ring. Additionally, SM05 lens tubes may be threaded onto the mount to accomodate thicker optics.

The rotation of the mount may be locked in position with a locking screw. The locking screw is activated using a 0.050" (1.3 mm) hex key. The kinematic adjustment is provided by three 1/4"-80 adjusters with brass bushings to provide smooth adjustment. Each adjuster may be locked with a locking screw using a 5/64" (2 mm) hex key.

Please note that while this mount is designed to hold Ø1/2" optics, the mount uses the same form factor as the KS1 Ø1" mirror mount in order to incorporate the rotation ring.

  • Six #8 (M4) Counterbored Mounting Holes Allow Left-Handed or Right-Handed Orientations
  • SM1-Threaded (1.035"-40) Rotation Ring with Locking Screw

The KS1RS is designed to hold Ø1" (25.4 mm) optics in situations where it is necessary to control the tip/tilt position as well as the rotation of the optic. This mount is ideal for polarization optics such as linear polarizers or wave plates. In addition, our Ø1" round cylindrical lenses may also be mounted in the KS1RS when it is necessary to adjust the angle of the line produced at the focal plane. The KS1RS features an SM1-threaded bore capable of mounting Ø1" optics up to 0.47" (11.9 mm) thick using the included SM1RR retaining ring. Additionally, SM1 lens tubes may be threaded onto the mount to accommodate thicker optics.

The rotation of the mount may be locked in position with a locking screw. The locking screw is activated using a 5/64" (2 mm) hex key. The kinematic adjustment is provided by three 1/4"-80 adjusters with brass bushings to provide smooth adjustment. Each adjuster may be locked with a locking screw using a 5/64" (2 mm) hex key.

Please note that while this mount is designed to hold Ø1" optics, the mount uses the same form factor as the KS2 Ø2" mirror mount in order to incorporate the rotation ring.

  • Four #8 (M4) Counterbored Mounting Holes Allow Left-Handed or Right-Handed Orientations
  • SM2-Threaded (2.035"-40) Rotation Ring with Locking Screw

The KS2RS is designed to hold Ø2" (50.8 mm) optics in situations where it is necessary to control the tip/tilt position as well as the rotation of the optic. This mount is ideal for polarization optics such as linear polarizers or wave plates. In addition, our mounted dove prisms with SM2 threading may also be mounted in the KS2RS to change the orientation of the rotated image. The KS2RS features an SM2-threaded bore capable of mounting Ø2" optics up to 0.47" (12.0 mm) thick using the included SM2RR retaining ring. Additionally, SM2 lens tubes may be threaded onto the mount to accomodate thicker optics.

The rotation of the mount may be locked in position with a locking screw. The locking screw is activated using a 5/64" (2 mm) hex key. The kinematic adjustment is provided by two 1/4"-80 adjusters with brass bushings to provide smooth adjustment. Each adjuster may be locked with a locking screw using a 5/64" (2 mm) hex key.

Please note that while this mount is designed to hold Ø2" optics, the mount uses the same form factor as the KS3 Ø3" mirror mount in order to incorporate the rotation ring.
