HP5517B  Laser Heads for Transducer Systems

The Keysight Technologies, Inc. 5517 series are Class II helium-neon lasers sources that provide highly stable
and accurate 633 nm wavelength light for precision dual-frequency interferometry. A variety of Zeeman split
frequencies, beam size, power levels, and special options are available to meet your systems requirements.
Keysight lasers are known for their reliability, with a mean time between failures (MTBF) of greater than 50,000
hours typical.
