PLANESERV
NanoStage is the planar surface motor traveling freely and precisely positioning on the flat surface stage that is enabled by contact-free structure featured by air-bearing.
The semiconductor laser interferometer built-in the slider not only offers the high accuracy and high speed responsibility but also allows to down-size the motor dimensions.
