The Nippon Pulse SCR nano-positioning stages from Micromech are available with an upgraded encoder. All stages are supplied standard with the upgraded Tonic Encoder, which includes limit switches as a part of the new read head and makes ‘end limits’ standard.
The previous standard encoder used optional and separate read switch end-of-travel limits. The improvements of the new encoders optimise performance and eliminate the need for extra wiring with the optional limit switches.
Other benefits of using this new ¬encoder on the SCR stages include improving interpolation feedback by four times, achieving five nm resolution without the use of a large RGB interpolator, and increased resolution and speed options.
The Tonic employs an interpolator into the connector as well as limit switches as a part of the head and ¬magnets are added internally to the stage to sense the limit.
