The Keysight 10898A Dual Laser-Axis Board provides the same resolution as the Keysight 10897B High Resolution Laser-Axis Board with increased slew rates and reduced noise. The increased stage velocity limits and low noise compared to previous laser systems offer premium positioning repeatability and accuracy for advanced applications such as IC fabrication equipment. Like its predecessor, the Keysight 10897B, the Keysight 10898A provides measurement resolution to lambda/2048 (0.3 nm) with the high resolution plane mirror interferometer.

For more detailed information on the 10898A, see page 10 of the Product Overview. 

  • Two high-performance laser axes on one board
  • Resolution to 0.31 nm
  • 2.7 m/s plane mirror slew rate capability
  • Sub-nanosecond variable data age
  • 5 MHz dual-channel data transfer
