10770A Angular Interferometer

The Agilent 10770A Angular Interferometer is a high accuracy plane mirror interferometer ideal for use in precision calibration applications. Used with the 10771A Angular Reflector in an 5529A Dynamic Calibrator system, the interferometer measures pitch and yaw motions along each axis that a machine tool or measuring machine travels. The system can help quickly locate and evaluate unwanted angular motion. The 10770A has a range of up to ±36,000 arc-seconds (±10°) when used with the 10771A Angular Reflector, with 0.1 arc-second resolution and a maximum transmitted beam deviation of ±30 arc-seconds. An alignment target is included to simplify setup.

As part of the 5529A system, the 10770A is a powerful diagnostic tool that helps find the causes of angular positioning errors – information that is critical in making replace or rebuild decisions for older machine tools.
