Application notes
Case studies
RLE interferometer enhances performance of Raith's latest e-beam tool
Raith improved the accuracy of its VB300 e-beam lithography tool by integrating Renishaw's RLE laser interferometer system. The upgrade reduced vibration-related errors and achieved positioning accuracy of less than 3 nm.

Laser encoder improves accuracy of optical connector measurement
Yagishita Giken improved the accuracy of its optical connector inspection machine by integrating Renishaw's RLE laser encoder, replacing a more complex and less precise interferometry system. The upgrade simplified installation and improved positioning resolution tenfold, from 0.1 µm to 0.01 µm.

Encoders hold the key to ultra-accurate motion control
Aerotech uses Renishaw's interferometric laser encoders to minimise measurement uncertainty by placing the measurement point closer to the point of interest. This enables highly accurate motion control and helps the company meet demanding precision requirements across a range of advanced applications.

VAD Instrument chooses Renishaw encoders for motion platforms
VAD Instrument selected Renishaw RLE laser encoder systems for its vacuum-compatible motion platforms, enabling highly accurate position feedback in demanding semiconductor and flat-panel display manufacturing environments. The encoder systems deliver reliable performance under ultra-high vacuum conditions, with nanometre-level precision and improved motion control for advanced inspection and process equipment.

Renishaw encoders support the latest in DUKIN's CMM design
DUKIN uses Renishaw's ultra-high precision RLE laser encoders in its CMMs to provide highly accurate position feedback, helping to minimise measurement errors and maintain metrology performance. The laser encoder technology supports the company's most demanding inspection applications in industries such as aerospace, automotive, micro-electronics and flat-panel displays by delivering exceptional precision and system stability.
