Renishaw has launched Atom — a non-contact optical linear and rotary incremental encoder system that combines miniaturisation with dirt immunity, signal stability and reliability. Suitable applications include laser scanning, co-ordinate measurement systems, semiconductor and flat-panel display production, motor drive systems, microscopy and the scientific research sector. It is ideally suited to a variety of space-critical motion control, inspection and metrology applications.

According to the company, the encoder achieves unmatched performance as a consequence of a design that avoids the many compromises traditionally associated with miniaturised encoders.

Atom is claimed to be the world’s first miniature encoder to use filtering optics with auto gain control (AGC) and auto offset control (AOC). This technology is found in Renishaw’s Tonic incremental encoder range, and is said to provide excellent signal stability and exceptional dirt immunity.

The company says that the Atom readhead delivers unrivalled metrology performance, offering class-leading accuracy with low sub-divisional error (SDE), low jitter, high signal stability and long-term reliability.
