SM1-Compatible Translation Mounts
The LM1XY(/M) translation mount utilizes M3-0.25 fine adjustment screws to provide ±1mm of travel perpendicular to the optical axis. The adjustment screws provide 250 µm/rev and feature a 5/64 hex for fine adjustments. This translation mount is internally SM1-threaded (1.035"-40) for use with our line of SM1-threaded components. The LM1XY holds Ø1" optics, up to 0.32" (8.0 mm) thick, against the back lip of the mount, using the provided SM1RR retaining ring.
The ST1XY translation mounts offer ±0.12" (±3.0 mm) of travel provided by one of three drive types: adjuster screw, micrometer, or differential drive. They utilize hardened tool steel components on all moving parts to ensure long-term, drift-free operation. The ST1XY is designed to connect with our extensive line of Ø1" SM1 Lens Tubes as well as our 30 mm cage assemblies to offer great flexibility when building optical systems.
The translating SM1-threaded carriage accepts optics up to 0.48" (12.2 mm) thick when using two SM1RR retaining rings (included). A stationary internal SM1 thread with 0.14" (3.5 mm) depth is present on the other side of the mount that allows for coupling to stationary SM1 Lens Tubes.
Three 8-32 (M4) tapped holes are provided on the bottom surface to allow direct mounting on our Ø1/2" Posts.

CXY1 and SM1 Lens Tube
Mounted in a 30 mm Cage System
The CXY1 XY Translator provides ±1 mm of travel perpendicular to the optical axis of a 30 mm cage system. This translation is actuated by two 3/16"-100 lockable adjusters. The movable carriage is internally SM1 (1.035"-40) threaded and directly accepts Ø1" optics up to 0.39" (10.0 mm) thick when secured using the included SM1RR retaining ring. The fixed back side is also threaded to allow SM1 lens tubes to be attached. The center carriage has been designed to offer pure X and Y translation. The mount features engraved vertical and horizontal tick marks to help maintain alignment of the mounting carriage.
The translation mount also features four through holes for use with our ER cage rods. Each cage rod is secured with one side-located 4-40 locking setscrew using a 0.05" (1.3 mm) hex key.

SM1-threaded lens tubes can be threaded onto both the front and back plate of the SPT1N slip plate mount.
The SPT1N(/M) Slip Plate Positioner is designed to provide coarse XY positioning of optical components. Both the front slip plate and back plate feature a center-located SM1-threaded hole ideal for use with our SM1 Lens Tubes. This design provides for manual adjustment only and is best utilized in conjunction with an alignment laser to monitor centricity. The threaded front plate is spring-loaded against the fixed, threaded back plate and can be locked into position via two locking screws. These locking screws can be threaded into the front side of the mount, or they can be removed and then re-threaded into the back side.
The front slip plate of the SPT1N(/M) accomodates Ø1" optics up to 0.07" (1.8 mm) thick, while the thicker back plate can hold Ø1" optics up to 0.19" (4.8 mm) thick. Unmounted optics can be secured with two SM1RR Retaining Rings (not included). The center-located SM1 (1.035"-40) tapped through holes in both the front and back plates also directly accept externally SM1-threaded components. Components should not be threaded past the end of either plate, as this will prevent the front slip plate from working properly. Please see the table below for the individual plate thicknesses.

The two locking screws can also be threaded through counterbores in the back plate of the SPT1T (shown here) or SPT1.
The SPT1(/M) and SPT1T(/M) Slip Plate Positioners are designed to provide coarse XY positioning of optical components within our 30 mm Cage Assembly System. This design provides for manual adjustment only and is best utilized in conjunction with an alignment laser to monitor centricity. The front plate can be locked into position against the fixed plate via two locking screws, which can be threaded from either the front or back side of the mount.
The SPT1(/M) accomodates Ø1" optics up to 0.08" (2.0 mm) thick, while the thicker front plate on the SPT1T(/M) can hold Ø1" optics up to 0.34" (8.6 mm) thick. Unmounted optics can be secured with SM1RR Retaining Rings, two of which are included with the SPT1T(/M). The center-located SM1 (1.035"-40) tapped through hole also directly accepts externally SM1-threaded components.
Thorlabs' CXYZ1(/M) Translation Mount features X-, Y-, and Z-axis travel and holds Ø1" optics, up to 0.39" (10.0 mm) thick, against the back lip of the mount using the provided SM1RR retaining ring. The 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 SM1 (1.035"-40) threaded 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 SM30RR Retaining Ring (sold separately); see the image to the right for more details.

The Z-axis position can be locked by threading an SM30RR retaining ring (sold separately) onto the internal threads of the rear knurled knob. This can be done using the SPW607 Spanner Wrench.
X and Y translation of the optic cell is actuated using the two 1/4"-100 fine adjusters, which can be locked using our LN25100 Locking Nuts (sold separately). Horizontal and vertical witness lines provide a reference for the XY alignment.

Translation of the Z-Axis Carrier Achieved by Rotating the Engraved Adjustment Dial
The mount has four through holes on 60 mm centers for use with our Ø6 mm ER cage rods, making it compatible with our 60 mm Cage Systems. Each cage rod mounting hole has two side-located 4-40 locking setscrews, which use a 0.05" hex key. The mount can easily be adapted to 30 mm Cage Systems by using the LCP02 Cage System Size Adapter. Two 1/4"-20 (M6) tapped holes are also provided on opposite sides of the XY adjusters for post mounting in right- or left-handed orientations.
Thorlabs also offers a 30-mm-cage-compatible XYZ translation mount for Ø1/2" optics, available here.
1.5 mm (0.06") Z-Axis Travel
Compatible with 30 mm Cage System
SM1 (1.035"-40) Threading for Compatibility with Our Extensive Line of SM1 Lens Tubes
Provides Translation Parallel with Optical Axis
Actuator Provides Smooth Adjustment
The flexure design of our SM1Z translator provides 1.5 mm of travel along the optical axis of our Cage Assembly System. The flexure approach ensures a stable, highly repeatable translation. The translating carriage, tapped with our SM1 (1.035"-40) thread, can directly accept Ø1" optics up to 0.18" (4.57 mm) thick. Thicker optics can be mounted to the SM1Z via our SM1 Lens Tubes.
Coarse movement is achieved by sliding the SM1Z along the rods of a cage assembly. Once positioned, four 4-40 setscrews apply locking force to the cage rods, firmly holding the mount in place. Fine movement of the lens carriage is accomplished with the precision micrometer head actuator. The actuator knob is graduated in 1 µm increments for a total of 50 increments per revolution.
For cage assemblies requiring a longer translation range along the optical axis, Thorlabs offers the CT1 stage capable of a full 1/2" (13 mm) of travel.
Maximum Stage Travel: 1/2" (13 mm)
Angular Deviation: <150 µrad
Micrometer Drive: 0.001" per Graduation (Imperial), 10 µm per Graduation (Metric)
Bearing Type: Ball Bearing
The CT1 Cage Translator is designed to be utilized in 30 mm cage systems that require translation along the optical axis of the cage. A modular design approach has been taken to allow a series of accessories to be mounted to the movable carriage of the CT1. Precision linear ball bearings are used to ensure smooth high resolution motion. A graduated micrometer provides 1/2" (12.7 mm) of linear translation and has 10 µm (0.001") graduations. The smallest incremental movement of the carriage is approximately 1 µm. As shown in the image, the CT1 stage also includes CT101 SM1 threaded mount. For more information on the included mount, see below.
The CT101 has an internal SM1 threading for mounting Ø1" components or externally threaded SM1 components, which includes the SM1 lens tubes. The mount is compatible with the MS103 Adapter Plate and with the CT1 30 mm cage Z axis translation stage. One SM1RR retaining ring, two 4-40 cap screws for securing the mount, and two removable dowel pins for alignment are included with each unit.
