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

Features:

• 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
• Agilent 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.
