(Renishaw: New Mills, UK) -- the RESOLUTE UHV is the latest ultra-high vacuum (UHV) compatible read head from Renishaw, offering true-absolute position feedback, submicron accuracy, and resolutions to 1 nm for both linear and rotary applications. The new range of RESOLUTE UHV encoders are constructed from clean vacuum-compatible materials and adhesives to give low outgassing rates and proven clean residual gas analysis (RGA), making them suitable for high-performance, semiconductor and scientific applications requiring vacuum compatibility to 10–10 Torr.

Like the standard range of RESOLUTE true-absolute encoders, the new ultra-high vacuum model determines position immediately upon switch-on, without the need for any movement or battery backup. Instant commutation means that axes are immediately under complete control after power loss, thus eliminating risks of unchecked movements or collisions—an advantage that is essential in applications such as wafer handling, where safe extraction of high value wafers is critical.
