The Keysight 10770A is a high-accuracy plane mirror interferometer engineered for precision angular motion measurement and calibration verification. Designed as a core component of the Keysight 5530 Laser Calibration System, it quantifies pitch and yaw deviations along machine tool and measuring machine axes, enabling detection of unwanted angular motion for maintenance diagnostics and rebuild assessment.

– Key Features
• Submicroradian resolution enables detection of minute angular deviations in precision machinery
• Dual angular measurement modes via 10771A reflector—base rotation and center rotation configurations
• Compact optical aperture (6 mm maximum beam) suits constrained mounting environments
• Stainless steel construction provides thermal stability critical for calibration repeatability
• Standardized 10785A mount interface ensures consistent system integration
– Typical Applications
• Pitch and yaw characterization on machine tool spindles and axes
• Coordinate measuring machine (CMM) qualification and verification
• Angular error mapping for precision grinding and milling equipment
• Periodic recalibration audits and machine rebuild validation
– Compatibility & Integration
The 10770A operates within the Keysight 5530 Laser Calibration System ecosystem and maintains backward compatibility with legacy Agilent 5530/5529 and Hewlett Packard 5529/5528 systems. Standard pairing with the 10771A Angular Reflector expands measurement capability across full angular range. The unit is optionally supplied as part of the 55281A Angular Optics Kit, which bundles the reflector and interferometer. Mounting via the 10785A interface ensures alignment stability throughout measurement cycles.
