Newport’s IMS-V linear stages offer long travel vertical motion of heavy loads up to 400 N. Using the same industry-proven technology as the IMS stages, the IMS-V stages provide very high performance in a cost-effective package, making them ideal solutions for precision industrial and laboratory applications.
All IMS-V series stages are optimized for maximum stability and performance using FEM analysis, resulting in a light and stable stage. While high in stiffness, the bending effect caused by different thermal expansion coefficients of the aluminum body and the steel rails is also minimized. Four-way equally load ball bearings provide superior support for high cantilevered loads, and the caged recirculating balls ensure maintenance-free operation without cage migration.
The drive system utilizes a 16 mm diameter lead screw with a proprietary wear resistant polyethylene terephthalate nut optimized for carrying high axial loads. The drive nut closely assimilates static and dynamic friction, minimizing the slip-stick effect found in classical lead screw systems. When used with the XPS motion controller, this guarantees better than 300 nm motion sensitivity, even at full load and over the life of the stage. The lead screw self locks to ensure superior in-position stability with no change of position at power off – typically found in braked, ball screw drives.
Precision position feedback is supplied by a linear scale with 0.1 µm resolution. This direct-read encoder provides superior accuracy and minimum hysteresis when compared to indirect feedback systems. The direct read system is impervious to position drift caused by motion-induced heating of the lead screw for improved accuracy and repeatability.
