Prism Mount Attachment for K6XS Mount
K6XS with K6A1
These kinematic mounts feature translation along three axes and rotation about three axes. Each adjuster includes a locking screw for stability. The mounting cell has an SM1- or SM2-threaded bore for mounting optics or SM-threaded components. The K6XS Ø1" mount also features four 4-40-tapped holes for attaching the K6A1(/M) prism mount. The prism mount attachment is designed to provide a 0.5" x 1.68" platform mounted to the rotation dial of the K6XS. The mounts are fabricated from black anodized aluminum.

Thorlabs' Green Initiative is aimed at reducing waste. To that end, we have begun to re-engineer our product packaging. These mounts are shipped in re-engineered packaging that minimizes the use of non-recyclable materials.
Over the course of a year, the re-engineered packaging across our product line is projected to reduce our CO2 footprint by more than 16,184 kg and reduce packaging by over 13,893 pounds! As we move through our product line, we will label re-engineered packages with our green Smart Pack sticker (above).
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.

6-Axis Kinematic Mount Usage
The 6-Axis Kinematic Optic Mounts are designed as general-purpose, high-precision positioners. The optic cell can be translated along or rotated about 6 axes, and each axis has a locking screw for stability. Both mounts use 1/4"-80 adjuster screws for pitch, yaw, and z-axis adjustment, and 3/16"-100 adjuster screws for x- and y-axis adjustment.
The translating cell of the K6XS has SM1 (1.035"-40) threading for attaching Ø1" lens tubes or mounting Ø1" (25 mm) optics up to 0.57" (14.6 mm) thick using the included SM1RR Retaining Ring, which can be tightened using an SPW602 or SPW606 Spanner Wrench (sold separately). The rotating dial has tapped 4-40 holes for attaching the K6A1 prism mounting attachment (sold separately below).
The translating cell of the K6X2 has SM2 (2.035"-40) threading for attaching Ø2" lens tubes or mounting Ø2" (50 mm) optics up to 0.53" (13.4 mm) thick using the included SM2RR Retaining Ring, which can be tightened using an SPW604 Spanner Wrench (sold separately).
In testing, the K6XS was shown to drift less than 15 µrad in 48 hours at typical environmental conditions, with a 2 °C temperature fluctuation. The X and Y axes on the K6XS cause less than ±50 µm of crosstalk when translated over their full range, while the X and Y axes of the K6X2 cause less than ±35 µm of crosstalk.

The K6A1 (K6A1/M) is a 0.5" x 1.68" (12.7 mm x 42.7 mm) platform designed to be mounted on the rotation ring on the K6XS 6-axis kinematic mount and our 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.

Clamping Arm Extension Posts with Metric Indicator Groove
Click for Details
Thorlabs' PM3(/M) and PM4(/M) Clamping Arms use a nylon-tipped setscrew with a 5/64" (2.0 mm) hex to secure optics to our kinematic platform mounts and V-clamps. The PM3(/M) accommodates optics up to 0.97" (24.6 mm) tall and features a 0.69" (17.5 mm) center-to-center distance between the post and the nylon-tipped setscrew. In contrast, the PM4(/M) accommodates optics up to 1.61" (40.9 mm) and features a 1.16" (29.3 mm) center-to-center distance between the post and the nylon-tipped setscrew. The maximum optic height of the PM3(/M) or PM4(/M) Clamping Arms can be extended using our PM3SP(/M) or PM4SP(/M) Extension Posts, respectively. These extension posts are identical to the posts included in each complete clamping arm.
The clamping arm for all items is held to the post using a flexure mechanism that locks with a 5/64" (2.0 mm) balldriver or hex key. The post also offers a through hole for added torque when tightening down the post. Please see the diagram above for additional information.
