Broadband Cube Beamsplitters
Broadband Cube Beamsplitters are formed from two right angle, 45° prisms permanently cemented together.
The hypotenuse is coated with a combination metallic and dielectric, partial reflection coating. An incident,
polychromatic beam is divided into reflected and transmitted components with a ratio (R/T) of 45/45 ± 5%. All
entrance and exit surfaces are coated with a high efficiency, broadband, anti-reflection coating.
