SCR Stages Get Encoder Upgrade

Effectively immediately, all Nippon Pulse SCR nanopositioning stages are available with a upgraded encoder, the Renishaw Tonic Encoder. Any stage built after September 1, 2010 and beginning with unit SN# 080210-001, will come standard with the upgraded Tonic Encoder.

The previous standard encoder was the Renishaw RGH24, which used optional and separate read end-of-travel limit switches. The move to the Tonic Encoder includes limit switches as a part of the new read head. This move optimizes performance and eliminates extra wiring needed with the optional limit switches. Because travel limits are included standard, there is no longer a need to pick them up as an option.

Other benefits of using this new encoder on the SCR stages include improving interpolation feedback by four times, achieving 5nm resolution without the use of a large RGB interpolator, and increased resolution and speed options.
