The Agilent/Keysight 10771A is an angular reflector accessory that enables precision angular rotation measurement within laser interferometry systems. It functions as a retroreflector component designed to work with compatible angular interferometers, reflecting laser beams back to detect changes in optical path length and calculate rotational displacement.
Technical Specifications
• Angular Measurement Range: ±10 degrees
• Alignment Tolerance: 20 arc-minutes for specified accuracy; up to 40 arc-minutes misalignment by autoreflection
• Mounting: Requires rigid mounting surface and adjustable mounts for precision alignment
• Beam Configuration: Angular interferometer must be positioned between laser head and reflector; laser beam enters interferometer either in-line or perpendicular to beam path
• Measurement Principle: Interferometric detection of optical path length changes as reflector rotates
– Key Features
• Retroreflector design for high optical efficiency in angular measurement setups
• Dual retroreflector spacing enables angle calculation from relative path length changes
• Compatible with adjustable mounting accessories for field alignment
• System accuracy dependent on proper alignment and associated interferometer performance
– Typical Applications
• Angular displacement and rotation measurement in precision alignment systems
• Calibration and verification of rotational stages and positioning equipment
• Angular metrology in optical systems requiring interferometric precision
– Compatibility & Integration
The 10771A integrates with the Agilent/Keysight 10770A Angular Interferometer and related laser measurement systems. Compatible mounting accessories include the 10785A Height Adjuster and Post, and the 10784A Base. Associated systems may require +15 V @ 7 mA and -15 V @ 7 mA power supplies.
