Non-Polarizing Cube Beamsplitters are formed from two right angle, 45。prisms permanentlycemented together. They are designed for applications in which it is necessary to maintain thepolarization characteristics of the incident beam. 
The hypotenuse is coated with an all dielectric,non-polarizing, partial reflection coating. 

An incident, unpolarized, monochromatic beam is dividedinto reflected and transmitted components with the specified intensity ratio. All entrance and exitsurfaces are coated with a high efficiency, narrowband, anti-reflection coating.

TO ORDER : Specify part number as follows: Substrate Code + Coating Code
Example: 25.4mm dimensions; 633nm; 70% R; 30% T: NP 26 K 063 70/30 

Other substrate materials, specifications, wavelengths and reflectance values can be provided upon request. Please contact our sales department for assistance.
