Thorlabs offers several XYZ translation mounts that provide coarse or precise XYZ translation when positioning optical components. These mounts can accept optics directly or optics mounted inside lens tubes with SM threading. Five of these mounts are equipped with both XYZ translation and tip-tilt adjustment (Item #s K5X1, K6X05, K6XS, K6X2, and KC1-S(/M)). Our 5- and 6-Axis mounts enable precision kinematic alignment of the optic cell along their respective axes.
For alignment applications in a 30 mm or 60 mm Cage System, we recommend our three cage-compatible, non-rotating, XYZ translation mounts for Ø1/2" and Ø1" optics (Item #s KC1-S(/M), CXYZ05A(/M), and CXYZ1(/M)). In particular, our KC1-S(/M) 30 mm cage-compatible kinematic mount with slip plate combines coarse XY translation with kinematic Z-axis and tip-tilt adjustment.
All translation mounts sold here can be post mounted using bottom- or side-located tapped holes or counterbores.

The K5X1 5-Axis Kinematic Optic Mount offers an optic cell that can be adjusted along 5 axes (pitch, yaw, and XYZ), each with a locking screw for stability. The translating cell has SM1 threading (1.035"-40) for attaching Ø1" mounted optics. The cell can also be used to mount Ø1" (Ø25 mm) unmounted optics up to 0.38" (9.5 mm) thick using the included SM1RR Retaining Ring, which can be tightened using an SPW602 or SPW606 Spanner Wrench (sold separately). The mount features engraved vertical and horizontal tick marks to use as an alignment aid for the mounting cell. For post mounting the K5X1 kinematic mount in a right- or left-handed configuration, two orthogonal #8 (M4) counterbores are provided. For information on the hex key sizes needed to adjust and lock the kinematic mount, please click on the Docs icon () below and select a drawing format.
For adjustment on all of the axes available with the K5X1 plus rotational adjustment, we offer the K6XS 6-Axis Kinematic Mount (sold below).

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.

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.

KC1-S Back View
- Slip Plate Provides ±1 mm of Coarse X and Y Adjustment
- ±4º Tip / Tilt, ±3 mm Linear Translation Along the Optical Axis
- Accepts Ø1" Optics
- Maximum Optic Thickness: 0.23" (5.8 mm)
- Compatible with Our 30 mm Cage Systems
- 8-32 (M4) Tapped Hole for Post Mounting
The KC1-S Kinematic Mount is designed with a SM1 (1.035"-40) threaded mounting hole with a front slip plate that enables direct mounting of optics up to 5.8 mm (0.23") thick using the included SM1RR Retaining Rings. Thicker optics can be accommodated by housing the optic in one of our SM1-Series Lens Tubes and then threading the lens tube into the front plate of the mount. Alternatively, since the back plate of the KC1-S Kinematic Mount features an oversized Ø1.32" bore, SM1 lens tubes can also be attached to the front plate from the rear of the mount without sacrificing angular adjustment. This threaded, kinematic mount comes with three adjusters with independently locking setscrews.
Both the front and rear plates have been machined with four clearance holes designed for direct compatibility with our 30 mm cage system standard. The cage rod holes in the front plate are sufficiently oversized to allow ±4° tip and tilt adjustment without cage rod interference. Once the desired position is achieved, locking setscrews on the rear plate can be used to secure the rods in place. In addition to 30 mm cage compatibility, the KC1-S Kinematic Mount is post mountable via an 8-32 (M4) tapped hole.
The KC1-S Kinematic Mount slip plate feature incorporated into this mount provides ±1 mm of coarse travel in X and Y with respect to the front plate, which enables additional freedom when setting an optic's position within a cage system. Three locking screws allow the user to lock the slip plate down once the desired location has been reached. The user should note, however, that loosening the locking screws may result in excessive coarse movement (slop) in the slip plate. For best performance, tighten the locking screws, and then release them only enough to allow for smooth operation of the slip plate.

The Z-Axis position of the CXYZ05A(/M) can be locked by threading an SM15RR retaining ring (sold separately) onto the internal threads of the rear knurled knob. This can be done using the SPW801 Spanner Wrench.
- Non-Rotating Translation in X, Y, and Z Axes for Ø1/2" or Ø1" Optics
- Internal SM Threading for Compatibility with Our Extensive Line of SM-Threaded Lens Tubes
- Compatible with Our 30 mm or 60 mm Cage Systems
- Two Tapped Holes for Right- and Left-Handed Post Mounting Orientations
Thorlabs' precise XYZ translation mounts offer non-rotating X-, Y-, and Z-axis travel. The CXYZ05A(/M) mount holds Ø1/2" (Ø12.7 mm) optics up to 0.31" (8.0 mm) thick against the back lip of the mount using the included SM05RR retaining ring. The CXYZ1(/M) translator holds a Ø1" (Ø25.4 mm) optic up to 0.39" (10.0 mm) thick in a similar manner using the included SM1RR retaining ring. XY functionality allows travel perpendicular to the optical axis, while the Z-axis functionality allows for compensation of focusing errors in applications such as fiber alignment or lens mounting. The optic cell has been designed to offer pure X, Y, and Z translation.
The optic cell is internally SM05-threaded (Item # CXYZ05A(/M)) or SM1-threaded (Item # CXYZ1(/M)), and is translated along the Z-axis by rotating the zoom adjustment dial on the back of the mount. The optic cell does not rotate during translation. An engraving is included on the knurled dial, indicating the direction that it must be turned for translating the optic cell forward and backwards. Laser-engraved tick marks spaced 0.25 mm apart are included on the optic cell for indicating the Z-axis position. The position can be locked using an SM15RR (Item # CXYZ05A(/M)) or an SM30RR (Item # CXYZ1(/M)) Retaining Ring (sold separately); see the image to the right for more details.
X and Y translation of the carriage on the CXYZ05A(/M) and CXYZ1(/M) mounts is accomplished using the two 3/16"-100 fine adjusters or 1/4"-100 fine adjusters, respectively. The nylon-tipped setscrew at the base of the 3/16"-100 adjusters for the CXYZ05A(/M) mount can be used to lock the X or Y translation using a 0.035" hex key. The 1/4"-100 adjusters on the CXYZ1(/M) mount are locked using LN25100 Locking Nuts (sold separately). For both sets of adjusters, horizontal and vertical witness lines provide a reference for the XY alignment.
All mounts have four through holes for use with our Ø6 mm ER cage rods, making the CXYZ05A(/M) compatible with 30 mm Cage Systems and the CXYZ1(/M) compatible with 60 mm Cage Assemblies. The CXYZ1(/M) has cage rod mounting holes with side-located 4-40 locking setscrews, which use a 0.05" hex key. The CXYZ05A(/M) has cage rod mounting holes with side-located M4 x 0.7 locking setscrews, which use a 5/64" (2.0 mm) hex key. The mounts can easily be adapted to different size cage systems by using the SP15 or LCP02 Cage System Size Adapter. Tapped holes are also provided on opposite sides of the XY adjusters for post mounting in right- or left-handed orientations.
