12.5mm NIR, 50R/50T, Non-Polarizing Cube Beamsplitter

Product Details Low Polarization Dependence: |Ts-Tp|<6% Constructed from High Tolerance Right Angle Prisms BBAR Coated Faces for Maximum Efficiency C-Mounted Visible and NIR Cube Beamsplitters Also Available TECHSPEC Broadband Non-Polarizing Cube Beamsplitters consist of a pair of precision high tolerance right angle prisms cemented together with a metallic dielectric coating on the hypotenuse of one of the prisms. The low polarization dependence of the metallic dielectric hybrid coating allows the transmission and reflection of S- and P-polarization states to be within 6% of each other. These beamsplitters feature anti-reflection (AR) coatings to maximize transmission across wavelengths ranging from 400-1620nm. TECHSPEC Broadband Non-Polarizing Cube Beamsplitters are spectrally flat across their specified wavelength ranges, reducing effects caused by changes in the angle of incidence or converging/diverging beams. These beamsplitters are ideal for applications that require splitting of light, such as interferometers and polarimeters.
