Broadband Cube Beamsplitters are formed form two right angle, 45。prisms permanentlycemented together. The hypotenuse is coated with a combination metallic and dielectric, partialreflection 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.

 

TO ORDER : Specify part number as follows: Substrate Code + Coating Code
