This fiber-coupled Beam Splitter 1 ⇾ 2 is a compact opto-mechanical unit that splits a fiber-coupled source into 2 output fiber cables with a fixed splitting ratio and a high efficiency. The input port is fiber-coupled to a PM fiber cable. Beamsplitters are also ideal for fluorescence applications, optical interferometry, or life science or semiconductor instrumentation., 50:50), they also differ. 101 Beam Splitters from 9 Manufacturers meet your specification.
