Agilent / HP / Keysight 5518A
5518A Laser Head and Receiver
This laser head and receiver is used in Agilent interferometer systems, is similar in function to the more recently introduced Agilent 5519A Laser Head.
It includes an internal measurement receiver, but it requires an external power supply.
This unit is used primarily as the laser source in Agilent 5528A Laser Measurement system.
It can also be used in place of an Agilent 5519A Laser Head when upgrading an Agilent 5528A system to an Agilent 5529A Dynamic Calibrator.
The Agilent 5518A has a laser beam diameter of 6 mm, and offers a vacuum wavelength accuracy of ±0.1ppm.
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 Agilent 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 positioning system improves product quality, increases yields, and facilitates manufacture of precision products.
