Irvine, California – August 11, 2005 – Newport Corporation, a worldwide leader in vibration and motion control solutions, today announced that its IMS-V linear stages offer long travel vertical motion of heavy loads up to 50 kilograms. In addition, the IMS-V stages provide very high performance in a cost-effective design, making them ideal solutions for precision industrial and laboratory applications including auto focusing, inspection, laser machining and test and measurement.

According to Jim Fisher, Director of Marketing for Newport’s Vibration and Motion Control Products, “Our New IMS-V high load vertical linear stages are an ideal solution for customers that want precise, reliable motion in their applications. Because they are machined from aluminum and optimized for maximum stability, these new solutions are light, very stiff and very stable stages that deliver superior thermal performance. In fact, when used with our XPS motion controller, the IMS-V stage guarantees better than 300 nm motion sensitivity, even when at load capacity, for the life of the stage.”

The IMS-V’s drive system utilizes a 16 mm diameter lead screw with a proprietary wear-resistant polyethylene terephthalate nut specifically designed for bearing high loads. The drive nut closely assimilates static and dynamic friction, minimizing the slip-stick effect found in classical lead screw systems. The lead screw self locks to ensure superior in-position stability with no change of position when the stage is powered down – something typically experienced with braked ball screw drives.

The stage’s precision position feedback is supplied by a linear scale with 0.1 µm resolution. This direct optical reading system provides superior accuracy and minimum hysteresis when compared to indirect feedback systems. The system also automatically compensates for position
drift caused by motion-induced heating of the lead screw for improved accuracy and repeatability
