Keysight / Agilent 55280A Overview
The Agilent 55280A Linear Measurement, used with the Agilent 5529A Laser Calibration System, includes the optical equipment needed to measure linear distance (displacement) and velocity. The kit contains an Agilent 10766A Linear Interferometer, two Agilent 10767A Linear Retroreflectors, mounting hardware, and an Agilent 10786A transit case.
The system measures the change in distance between the interferometer and the retroreflector. Prior to movement, any point can be defined as a measurement starting point.
The Agilent 55290A can be used to calibrate the positioning accuracy of numerically-controlled machine tools and coordinate measuring machines. With its extreme accuracy and resolution, it can also be used as a de facto standard for calibrating length standards.
Features:
- Linear Distance Measurement Accuracy: Distance measurements will be accurate to within the following tolerances (error band) depending on the velocity of light compensation method and operating temperature. Values shown apply at a known material temperature with known coefficient of thermal expansion. If automatic material temperature sensing is used, the system error will be increased by Te (ppm).
- Te(ppm) - (coeff. of expansion in ppm/deg. C) X (average sensor error in deg. C
- Velocity of Light (VOL) Compensation Method
- Manual Operating (VOL Exactly Automatic Temperature Known in -- Using Agilent 10751A/B Range (deg. C)* Beam Path-- Air Sensor)
- 20 (±0.5) ±0.1 ppm*** ±1.5 ppm
- 15-25 ±0.1 ppm*** ±1.7 ppm
- 0-40 ±0.1 ppm*** ±3.0 ppm
- * Temperature of all system components is stabilized anywhere within the temperature range shown.
- ** Agilent 10751A/B mounted in recommended orientation. Humidity switch set to most closely matched actual conditions. 12 month calibration interval assumed.
- *** ±0.02 ppm if the Agilent 5518A Laser Head is factory calibrated to MIL STD 45662.
- High measurement accuracy
- Calibration for many length standards
- One optical setup accomplishes both displacement and velocity measurements
- Included mounting accessories simplify fixturing for linear and other system optics
