FiberPort Accepts FC/PC and FC/APC Patch Cables PFS-FFT-1X2-1550 Kit for 1200 - 1600 nm PFS-FFT-1X2-780 Kit for 700 - 1000 nm ![]() Please Wait
![]() Click to Enlarge These beamsplitter kits are shipped with their polarizing beamsplitters and half-wave plates packaged seperately. ![]() Click to Enlarge The polarizing beamsplitters are mounted on a kinematic base with tip, tilt, and fine rotation adjustment screws. Features
These Variable Polarization Beamsplitter Kits are based on Thorlabs' FT-51X60 Multi-Axis FiberBench. A PM fiber can be attached to the input FiberPort, which collimates the output. The FiberPorts included with these kits have wide key slots. The polarization of this beam is then rotated with a half-wave plate. By changing the orientation of the wave plate, the ratio of the vertical to horizontal State of Polarization (SOP) is changed, which then affects how much signal is transmitted and reflected through the polarizing beamsplitter cube. These beamsplitters have extinction ratios of >1000:1 (TP:TS). The average p-component transmission is >90% while the average s-component reflectance is >99.5% for each beamsplitter. Please see the Graphs tab for more information. The split ratio is continuously variable from 0 to 30 dB and is dependent on the polarization extinction ratio from the input PM fiber and the spectral line width when Δλ ≤ 3 nm. Assembly
