The flexure design of our SM1Z translator provides 1.5mm 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" (4.57mm) thick. Thicker optics can be mounted to the SM1Z via our SM1 series 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 1µm 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" (13mm) of travel.

Compatibility: Thorlabs offers 16mm, 30mm and 60mm cage systems designed for 1/2", 1" and 2" optical components (respectively). The parts on this page are compatible with our 30mm cage system and utilize 6mm ER cage rods. In addition, the SM1Z mount is equipped with SM1 Lens Tube threading which allows for easy mounting of lens tube compatible components.
