SM2-Compatible Translation Mount




  • Ø2.035"-40 Threading
  • Mount SM2 Lens Tubes
  • Mount Ø2"(Ø50 mm) Optics

This page is a compilation of all of Thorlabs' SM2 (2.035"-40) threaded translation mounts in order to allow for the quick selection of a translation mount if SM2 threading is a primary requirement. Thorlabs also has similar compilations of SM threaded translation mounts for Ø1/2" (12.7 mm) and Ø1" (25 mm) optics. If SM threading is not a primary requirement for the translation mount, consider using the manual or motorized translation mount navigation menus.

 


Post-Mountable SM2-Threaded XY Translator


* Designed to Center Ø2" (50 mm) Optics in a Beam Path
* High Resolution Adjusters Provide 250 µm/rev for Micron Sensitivity
* SM2 (2.035"-40) Threads Compatible with Our Extensive Selection of SM2 Lens Tubes
* Wobble: * Max Optic Thickness: 12 mm

This mount utilizes two M3 x 0.25 fine adjustment screws to provide ±1 mm of travel along both axes perpendicular to the optical axis. The 250 µm/rev adjustment screws have 5/64" hex socket in the back end of each screw so that hex key may be used to achieve for better feel than the thumb screw knob when making small incremental movements. The mounting bore for the optic is SM2 (2.035"-40) threaded, which makes the mount compatible with SM2 lens tubes and other SM2-threaded components. The optic is held in the mount using the included SM2RR retaining ring.

 

XY Translator for 60 mm Cage Systems

 

  • Accepts Ø2.00" (Ø50.8 mm) Optics Up to 0.59" (15.0 mm) Thick
  • ±2 mm Travel in X and Y without Rotation
  • 3/16"-100 Lockable Adjusters

The CXY2 XY Translator provides ±2 mm of travel perpendicular to the optical axis in a 60 mm cage system. The moveable carriage is internally SM2 (2.035"-40) threaded and accepts Ø2" optics up to 0.59" (15.0 mm) thick. Thicker optics can be mounted into an SM2 lens tube, which then may be attached to the front of the translator. The fixed backside is also SM2 threaded to allow SM2 lens tubes to be attached. While the mount features a non-rotating center carriage, the mount does feature horizontal and vertical tick marks to ensure proper alignment of the moveable carriage.

 

XY Slip Plate Positioner for 60 mm Cage Systems

 

  • ±2 mm of X and Y Manual Adjustment
  • Lockable Design
  • Center-Located SM2 (2.035"-40) Internal Threading
  • Tapped Mounting Hole
  • 60 mm Cage System and SM2 Lens Tube Compatible

The SPT2 Slip Plate Positioner is designed to provide coarse XY positioning of Ø2" optical components within our 60 mm cage assembly system. The SM2-threaded bore can mount optics up to 0.30" (7.6 mm) thick using two SM2RR retaining rings (not included). This design provides manual adjustments of ±2 mm of travel and is best utilized in conjunction with an alignment laser to monitor the centricity. The images below detail how to adjust and lock the SPT2.
