Renishaw: RSLA stainless steel linear scale A-9765-4400
RSLA absolute high accuracy stainless steel scale is compatible with Renishaw’s revolutionary, true absolute optical encoder system, RESOLUTE™. RSLA stainless steel scale is available in a range of lengths up to 5 m, with 5 m lengths having an overall accuracy better than ±4 µm - an industry first! Combined with readheads featuring low sub-divisional error (±40 nm), advanced optics, resolution to 1 nm and simple installation and setup, RSLA provides outstanding motion control performance. RSLA offers the ease of use of a tape scale yet has the performance of a glass spar; the scale can be coiled for simple storage and handling yet behaves as a spar once uncoiled. The choice of mechanical or adhesive mounting makes RSLA perfect for long-travel applications where metrology cannot be compromised.Shatter-proof RSLA high-precision stainless steel scale, offering higher accuracy than glass scales and long lengths up to 5 m, with ±4 µm accuracy over a complete 5 m length

System features

• Single track optical absolute scale • 30 µm nominal scale pitch ensures exceptional motion control performance • Robust special composition stainless steel with defined coefficient of thermal expansion (10.1 ±0.2 µm/m/°C@20 °C) • Coilable for simple storage and handling • Available in defined lengths up to 5 m • ±40 nm sub-divisional error for smooth velocity control • Resolution to 1 nm • Maximum speed of 100 m/s
What is RSLA30 scale?

RSLA30 is a stainless steel spar scale featuring 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 ±4 µm over a 5 m length. It can also be coiled for simple storage and handling yet once uncoiled behaves as a spar scale.
System designers can choose between specially formulated adhesive tape or mechanical clips to suit mounting requirements. Both mounting methods allow for independent thermal expansion to that of the substrate
