Fiber optical beam splitter FBS

       Fiber-optic beam splitters split the radiation guided in a singlemode fiber into two singlemode fibers. Fiber-optic beam splitters from Schäfter+Kirchhoff have a splitting ratio of 50:50 (± 5 %) as standard and are provided for wavelengths between 460 and 1500 nm. The bandwidth is ±1 % of the design wavelength. Insertion loss is approximately 1 dB at 460–700 nm and 0.5 dB at 700–1550 nm.

       The fiber-optic beam splitters have 3 or 4 ports, respectively, and are ideal for use in interferometric or other set-ups. The Ø3 mm cables have Kevlar strain-relief and the connectors may be of type FC-PC, FC-APC (or ST, SMA, E2000 or DIN-AVIO) or core-aligned (<0.5 μm). Customized products, such as with a different number of output ports, are available on request.
