Vacuum Stages feature encoder to detect stepper motor stall.

Press Release Summary:




Compatible to 7 x 10e-6 torr vacuum, LTA Series Actuators and Model URS50B Rotation Stage are designed for integration in critical sample positioning or beam management processes in vacuum environments. Models LTAHSPPV6 and LTAHLPPV6, rated at 10,000 MTBF, provide sub-micron minimum incremental motion and uni-directional repeatability. Capable of 360° continuous motion at 4°/sec, Model URS50BPPV6 can accommodate 5 kg loads and provides minimum incremental motion of 0.0015°.

Newport Introduces Standard Vacuum Stages



Irvine, CA - Newport Corporation, a worldwide leader in lasers and photonics solutions that Make, Manage and Measure Light®, announces the new vacuum- compatible LTA series actuators and the URS50B rotation stage for research and industry. These products are compatible to 10 x e-6 hPa (7 x 10e-6 torr) vacuum and are designed for integration in critical sample positioning or beam management processes in vacuum environments. These newly-designed vacuum stages feature a motor-mounted encoder that is extremely useful in detecting the stall of a stepper motor since the stage is not accessible when installed inside a vacuum chamber. The encoder also offers improved position repeatability, a critical factor in many research and commercial applications in vacuum environments.

The LTAHSPPV6 and the LTAHLPPV6 actuators are extensions of the popular and reliable LTA actuators (with non-rotating tips), and are rated at 10,000 hrs MTBF. Compatible with other vacuum-compatible manual stages, both actuators provide sub-micron minimum incremental motion (MIM) and uni-directional repeatability.

The compact URS50BPPV6 rotation stage complements Newport's higher load capacity URS75BPPV6. The newer model is capable of 360 degrees continuous motion at 4 degrees per second, an MIM of 0.0015 degrees, and can accommodate 5kg loads. The 4-mounting hole locations enable top mounting and enhance the stage's cantilevered load capacity. This stage is rated at 20,000 hrs MTBF.

The new vacuum-compatible products can be supplied with Newport's motion controller products from the single-axis SMC100PP to the 8-axis XPS Universal Controller.
