Renishaw: RSLA stainless steel linear scale A-9765-0020
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.
