What is RESOLUTE UHV? RESOLUTE UHV brings absolute encoder technology to Ultra-High Vacuum applications, allowing customers to achieve higher throughput, reduce risks of damage and increase dependability. RESOLUTE outperforms all other absolute encoders that are designed for UHV environments. Capable of 1 nm resolution and up to 100 m/s, RESOLUTE provides a specification that breaks new ground in encoder technology. What is RELA30 scale? RELA30 is a spar scale manufactured from ZeroMet, a low expansion nickel/iron alloy, featuring our 30 µm pitch absolute scale code. It is comparable to fine pitch glass scales and offers a total accuracy (including slope and linearity) better than ±1 µm up to 1 m length. ZeroMet has a thermal expansion coefficient of 0.75 ±0.35 µm/m/°C at 20 °C. System designers can choose between specially formulated UHV compatible adhesive tape or mechanical clips to suit mounting requirements. Both mounting methods allow for independent thermal expansion to that of the substrate.
