Beamsplitter Cubes are constructed by cementing two right angle prisms together with the appropriate interference coating on hypotenuse. The absorption loss to the coating is minimal. Transmission and reflection approach 50% (average) though the output is partially polarized.
We provide beamsplitter cubes with dimensions as small as 1mm.
