nPS35 Stage
Compact Stages with Cross-roller Bearings
The nPS35 are extremely compact stages with cross-roller bearings. They are offered in both lead screw (LS) and ball screw (BS) versions. The lead screw option allows for lower cost and is especially helpful in vertical applications where self-locking is needed. The ball screw option is available for applications requiring higher efficiency, duty cycle or speed.
The mounting pattern allows for seamless integration with the nPCube piezo stage. Combining the nPS35 stages with any X, XY or XYZ version of the nPCube creates multi-axis systems that offer up to 12 mm of positioning range and high-speed scanning necessary in Photonics, Precision Assembly and Biomedical applications.
