Beamspitters
Narrow Band Beamsplitter Cube | Broadband Beamsplitter Cube | Narrow Band Beamsplitter Plate | Broadband Beamsplitter Plate
The beamsplitter cube can only function well when input light is random polarized (natural light). If the input light is linear polarized, the output T/R will be not 50/50.
