HP 5517B Laser Head

The HP 5517B Laser Head, used in HP interferometer systems, offers a vacuum wavelength accuracy of +/- 0.1 ppm, 500 mm per second axis velocity for linear optics, and beam diameter of 6 mm. 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 HP 5517B 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.
