Renishaw Inc.

The RESOLUTE absolute optical encoder system from Renishaw Inc., Hoffman Estates, IL, is capable of 27-bit resolution at 36,000 rpm. The fine-pitch system offers excellent dirt immunity while delivering 1 nm resolution at up to 100 m/s for both linear and angle encoding applications. Features include a single-track optical scale that lets the encoder acquire absolute position immediately upon switch-on, sophisticated new optics to read a 30 µm scale for jitter <10 nm RMS and SDE of ±40 nm, an IP64-rated readhead, and a built-in independent position checking algorithm. A temperature sensor in the readhead measures heat build-up.
