Newport has announced its new vacuum compatible LTA series actuators and the URS50B rotation stage for the research and industry markets.
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 useful in detecting the stall of a stepper motor since the stage is not accessible when installed inside a vacuum chamber. 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 hours mean time between failure (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.
