High-speed and high-resolution Scale-Image

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 wavelength of approx138nm, outperforming light wave interferometer systems
  • High stability, unaffected by humidity, air pressure and air disturbances
  • Reference point accuracy : ±0.1μm
  • Scale accuracy : ±0.04μm or better (measuring length : 40 mm)
  • Completely non-contact design Return error is virtually eliminated.
  • Special non-magnetic and vacuum-compatible models available
  • Using low expansion glass : -0.7 x 10-6/ ? (measuring length : 10 to 420 mm)
