XYZ Translation with Pitch/Yaw Adjustment and Rotation
SM05- (0.535"-40), SM1- (1.035"-40), or SM2- (2.035"-40) Threaded Versions
Prism Mounting Attachment Available for SM1 Mount
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 SM05-, SM1-, or SM2-threaded bore for mounting optics or SM-threaded components. The K6XS Ø1" mount also features four 4-40-tapped holes on the rotation dial for attaching the K6A1(/M) prism mount (available separately below). The prism mount attachment includes a 0.5" x 1.68" platform and a PM3(/M) clamping arm, as well as the screws and hex key needed to secure it to the K6XS mount. The mounts are fabricated from black anodized aluminum.
Thorlabs' Smart Pack Initiative is aimed at minimizing waste while providing adequate protection for our products. By eliminating any unnecessary packaging, implementing design changes, and utilizing eco-friendly materials, this initiative seeks to reduce the environmental impact of our product packaging.
The updated K6XS packaging primarily consists of recycled paper and cardboard and weighs 64% less than the original packaging. This weight change results in a 75% reduction in CO2 emissions per year, based on typical product sales.
As we move through our product line, we will indicate re-engineered, eco-friendly packaging with our Smart Pack logo, which can be seen 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, piezo inertia motor, or an Elliptec™ resonant piezo motor. Each offers 360° of continuous rotation.

#8 (M4) Counterbores for Post Mounting
These 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. All three 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 rotating optic housing is engraved with a graduated scale. Refer to the table below for detailed specifications.
The rotating dial of the K6XS mount has tapped 4-40 holes for attaching the K6A1 prism mounting attachment (sold separately below). 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 K6X05 and K6X2 cause less than ±35 µm of crosstalk.
If higher adjustment resolution is desired for pitch, yaw, or z-translation, the three 1/4"-80 adjusters can be switched with DAS110 or DM22 Differential Adjusters.
K6A1 Prism Accessory Mounted onto a K6XS 6-Axis Mount
Mounts on the Face of the K6XS Translating Cell
0.5" x 1.68" (12.7 mm x 42.7 mm) Platform
1/4" (6 mm) Adjustment Range
The K6A1(/M) platform accessory is designed to be mounted on the rotation ring on the K6XS 6-axis kinematic mount and our 30 mm cage-compatible rotation mounts using the included 4-40 screws and hex key. The platform has a height adjustment range of 1/4" (6.3 mm) so that the mounted optic can be positioned on the axis of rotation. Four 6-32 (M4 x 0.7) tapped holes at the corners of the platform surface can be used to mount the included PM3 (PM3/M) prism clamping arm or other optomechanics.
Extension Posts Available to Increase Max Optic Height
PM3SP(/M) with PM3(/M): Hold Optics up to 2.21" (56.1 mm) Tall
PM4SP(/M) with PM4(/M): Hold Optics up to 3.61" (91.7 mm) Tall
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.
