5518A Laser Head and Receiver

The Keysight 5518A laser head, used in Keysight interferometer systems, is similar in function to the more recently introduced Keysight 5519A Laser Head. It includes an internal measurement receiver, but it requires an external power supply. The Keysight 5518A is used primarily as the laser source in Keysight 5528A Laser Measurement system. It can also be used in place of a Keysight 5519A Laser Head when upgrading a Keysight 5528A system to a Keysight 5529A Dynamic Calibrator. The Keysight 5518A has a laser beam diameter of 6 mm, and offers a vacuum wavelength accuracy of ±0.1 ppm. The laser head uses a proven long-life laser tube with a demonstrated Mean Time Between Failure (MTBF) of greater than 50,000 hours of operation.

The Keysight 5518A is configured with appropriate optics and system electronics to build a laser interferometer system that meets the unique physical layout and measurement requirements of individual applications. The custom pos
