Standard Cube Beamsplitter

Cube beamsplitters are manufactured by optically bonding together two precision right angle prisms. The hypotenuse surface is designed with a defined transmission and reflectance ratio coating to separate beams of incident light. An anti-reflection coating has also been applied to each face of the cube to achieve less than 0.5% reflection loss per surface. Compared to Plate Beamsplitters, they are easily mounted, more durable and allow the optical path of the system to be shorter.
