Features

SR50 Series Stages

The SR50 stages feature minimum incremental motion of 0.004°, which may be achieved with either DC Servo or open-loop stepper motors (half-step mode). The motor is folded inside the stage body to give an extremely small footprint for a stage at this level of precision. The stages are equipped with a hardware origin, allowing the stage to return to a reference home position to within 0.01°. SR50 stages can run in continuous rotation mode.

PR50 Series Stages

The PR50 stages are a cost-efficient alternative to the SR50 for applications that do not require the high-resolution and precision of the SR50, or for applications that could benefit from higher speeds up to 20°/s. The PR50 stages feature angular resolution of 0.01°, which may be achieved with either DC Servo or open-loop stepper motors in half-step mode. The stages are equipped with a hardware origin and allow for continuous rotation of 360°.

Vertical Mounting

The optional EQ45 bracket can be used for vertical mounting of a PR50 or SR50 stage.

Two PR50 stages with an EQ45.

CONEX Controller Versions

We offer versions of these stages integrated with a CONEC controller. The CONEX controller comes with a USB cable and a CONEX-PS-CB for daisy-chaining modules. Power supply to be ordered separately.

Central Aperture

The central aperture is threaded 1.063-20 in. SR50 and PR50 stages are shipped with two, same diameter retaining rings to allow mounting of any Ø25.4 mm diameter optics within the aperture. Four M3 holes allow for attachment of custom top plates.

Proprietary Ball Bearing Design

The lightweight, low profile design incorporates an aluminum body with pre-loaded ball bearings. This proprietary ball bearing design provides smooth rotation with minimal wobble. A precision ground worm gear produces consistent driving torque to the rotating carriage and eliminates variations in motor current.

Metrology Report Included at No Additional Cost

Newport guarantees specification values which are measured and recorded following ASME B5.57 and ISO 230-2 standards. The typical performance values are two times better than the guaranteed specifications.
