Coaxial System XY Translation Mounts STXY1-A

The STXY1-A/S/D models are all equipped with two adjusters, driven by a threaded pair/micrometer head/differential head respectively. The differential drive head consists of two internal lead screws for differential drive; one advances the spindle with a precision of 500 µm per revolution, while the other retracts it with a precision of 450 µm per revolution. Therefore, one full rotation of the graduated knob results in a total spindle displacement of only 50 µm, enabling precise positioning. During fine adjustment with the differential head, coarse adjustment can be locked using a hand-tightened nut. Suitable for mounting Ø25.4 mm optical elements, it allows fine-tuning of the optical element position in the X and Y directions with a travel range of ±3 mm. The XY translation module features an SM1 internal thread and includes two SM1R retaining rings for mounting optical elements with a maximum thickness of 12.2 mm. It is compatible with Ø25.4 mm lens tubes. The front panel center has an SM1 internal thread, compatible with Ø25.4 mm lens tubes. This mount has three M4 threaded holes, allowing direct mounting onto optical posts, and is also compatible with 30 mm cage systems. The XY translation mount stage dimensions are 66×66 mm. Note: The STXY1-S drive method is micrometer head drive. Due to manufacturing tolerances in the micrometer head, there may be deviations in the XY travel range of the mount.
