The Keysight 10704A is a cube corner retroreflector engineered for single-beam laser interferometry measurements. This optical component reflects incident laser beams back along their original axis, enabling precision positioning and dimensional metrology when integrated with compatible interferometer systems, laser heads, and control electronics. Designed for beam diameters of 6 mm or less, the 10704A weighs 10.5 g and features optical elements bonded to stainless steel housings using low volatility UHV-compatible adhesive, making it suitable for vacuum environments.

– Compatibility & Integration
The 10704A requires a complete system comprising a laser head, interferometer electronics, and control software. Primary integration is with the Keysight 10705A interferometer. The retroreflector mounts within measurement fixtures designed to position it along the optical axis. Alternative cube corner options include the 10713C (1/2 inch) and 10713D (1/4 inch) for applications with different mounting constraints or mass requirements.
