Beamsplitter Cube Description
Beamsplitter Cube is manufactured from two triangular glass prisms. These prisms are bonded at their bases using adhesives based on polyester, epoxy or urethane. It typically contains two or more optical elements such as mirrors or prisms. It operates by reflecting a portion of the incident beam and transmitting the remainder. The reflectivity and the transmittance are determined by the optical elements or the coating on the outer surfaces.
