This unit
The Keysight 5519B is a two-frequency Helium-Neon laser head engineered for precision displacement measurement and calibration in machine tool, CMM, and linear metrology applications. This continuous-wave HeNe laser delivers stable, accurate output across thermal cycles and operational lifetime by employing dual-frequency technique to suppress beam intensity fluctuation errors. The 5519B integrates into the Keysight 5530 Laser Calibration System and Agilent 5529A/55292A Dynamic Calibrator platforms, providing Class 2 laser output with exceptional wavelength stability and repeatability.
