Universal Beam Source for Interferometry and Frequency Standards
The Sch?fter+Kirchhoff HeNe lasers and fiber optics are polarizationmain taining and provide a high coupling effi ciency with extremely resilient transport capabilities. A large selection of coupling lenses is provided that match the different laser beam diame ters with the particular PM fiber chosen for use. Both ends of the singlemode fibers have 8°-polish (connectors Type FC-APC) in order to minimize laser back-reflection and power noise effectively.
