Description

High-speed and high-resolution, while maintaining stable, ultraprecision measuring. Ideal for precision stages, semiconductor inspection/manufacturing systems, and ultraprecision processing machines. High-resolution scale with signal pitch of approx. 138 nm, outperforming light wave interferometer systems High stability, unaffected by humidity, air pressure and air disturbances Reference point accuracy: ±0.1µm Non-contact design eliminates return error. Measuring length: 9 types (-R/-RS) Measuring length: 10 types (-N/-NS) Special non-magnetic and vacuum-compatible models available Using low expansion glass: -0.7 x10-6 °C (measuring length: 10 to 420mm) Resolution: 2.1 pm
