The RSLM linear encoders are a new addition to Renishaw’s SiGNUM range of optical encoders. The company said the RSLM linear encoders overcome limitations of glass scale with superior durability, ...

The crossed roller bearing stage integrates the piezoelectric SQUIGGLE motor and glass scale encoder. The device offers a maximum speed of 2 mm per second and 15-mm travel.

The low thermal expansion (3.3 ppm/°C) precision glass scale encoder results in high-accuracy and repeatable positioning over long periods of time. The linear encoder is available with amplified sine ...

Glass scales typically have smaller manufacturing and installation errors than tape scales. However, glass scales offer little immunity to dirt and contamination by fingerprints and dust.

The M-660 direct-drive stage features a height of only 14 mm, speed to 720 degrees per second and resolution to 4 micro radian with a direct metrology glass scale encoder.

Two part stage design with cross roller bearings includes a direct drive linear motor and glass scale encoder with 40 MHz encoder processing for sub-nanometre resolution and jitter-free scanning ...
