10896B Laser Compensation Board for VMEbus

Product Status: Obsolete | View Service Options
This product is no longer available

No replacement found for this product.


The Keysight 10896B compensation board increases the accuracy and repeatability of Keysight's VME-based laser interferometer positioning systems. Using your own or Keysight's environmental sensors, the Keysight 10896B detects and compensates for changes in the system's operating environment. The Keysight 10751C/D air sensor can be used to provide an accuracy up to ±1.5 ppm. Keysight 10757D/E/F material temperature sensors are used to compensate for thermal expansion errors. 

  • Compensation
  • Environment:
  • Pressure: 760 mm +/-25 mm Hg
  • Relative Humidity: 50% +/-10%
  • Temperature: as shown in table
  • Measurement Accuracy*
  • +/-0.1 deg. C +/-1.0 deg. C +/-5.0 deg. C
  • No compensation** (@20 dgrees C) +/-9.0 ppm +/-9.9 ppm +/-1.7 ppm
  • Keysight 10751C/D Air Sensor (@20 degrees C)+/-1.5 ppm +/-1.6 ppm (typical) +/-1.7 ppm
  • Wavelength Tracking +/-0.15 ppm +/-0.19 ppm +/-0.44 ppm
  • Compensation***
  • Measurement in Vacuum +/-0.1 ppm +/-0.1 ppm +/-0.1 ppm
  • Measurement in Vacuum with Factory Calibration of Laser Head to MIL STD 45662 +/-0.02 ppm +/-0.02 ppm +/-0.02 ppm
  • * These accuracy specifications include the laser head term, but exclude electronics accuracy and interferometer nonlinearity terms.
  • ** No compensation means that no correction in compensation number occurs during environmental changes.
  • *** System accuracy equals these values (measurement repeatability) for a calibrated laser head accuracy of initial compensation value.
