High Resolution Adjusters Provide 250µm/rev. for Micron Sensitivity Compatible With Our Extensive Selection of SM05, SM1, and SM2 Lens Tubes Designed to Center Ø1/2", Ø1", and Ø2" Optics in a Beam Path
Wobble: <100 µradThorlabs offers a variety of optic mounts for XY travel. These mounts utilize M3-0.25 fine adjustment screws to provide ±1mm (LM05XY and LM1XY) or ±2 mm (LM2XY) of travel perpendicular to the optical axis. The adjustment screws provide 250 µm/rev, and there is a 5/64 hex socket in the back end of each screw. An L-wrench may be used to achieve small incremental movements. All XY mounts utilize SM series threads to secure the optic, making them compatible with virtually any externally threaded SM series component. The LM1XY (LM2XY) accepts optics up to 8 mm (13 mm) thick.
- Compact Design, ±0.12" (±3.0 mm) Travel
- Compatible with Our Ø1" SM1 Lens Tubes
- Compatible with Our 30 mm Cage Systems
- 4-40 Taps on Front and Back Provide 30 mm Cage Compatibility
The ST1XY translation stage utilizes 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. Three 8-32 (M4) tapped holes are provided on the bottom surface to allow direct mounting on our Ø1/2" Posts. Each mount comes with one SM1RR retaining ring.

- Designed Specifically for Use with the ST1XY Series of XY Translators (Featured Above)
- Connect Two Internally Threaded Cage Components with ER Rods
- SM1 (1.035"-40) Threaded Through Hole
- Four 4-40 Screws Included
The ST1CP is a bolt-on adapter designed specifically for use with the ST1XY-series of XY translators. Like our ERSCA adapter, this plate can be used to connect two internally threaded cage components with ER rods. First thread the four included 4-40 screws through the ST1CP through hole and into the internally bored side of the ER rod (as shown in the figure to the left). Then, remove the back plate on an ST1XY stage and secure this adapter plate in its place using the four outer 2-56 counterbored through-holes. Once attached, this adapter plate keeps the cage and any SM1-threaded component attached to the adapter plate stationary, while enabling an optic inside the ST1XY stage to move relative to these fixed components.
Alternatively, this adapter can also be attached to the front side (i.e., the side without the removable mount) of an ST1XY stage using the included 4-40 screws. In this case, the front side of the ST1XY stage will no longer be cage compatible (although the back side still is). However, the advantage of this configuration is that two SM1-compatible components can be attached to the ST1XY stage (one on each side) and an optic inside the stage can be moved relative to these fixed components.
