Beamsplitter Plate

A beamsplitter plate type is an optical window with semi-transparent mirrored coating to break a beam into two or more separate beams. A beam-splitter will reflect a portion of the incident energy, absorb a relatively small portion, and transmit the remaining energy . Beamsplitter plates have very neutral color characteristics and are often referred to as beam-splitters plate.
