Nonpolarizing Cube Beamsplitters

Nonpolarizing cube beamsplitters consist of a pair of precision right-angle prisms that have been carefully cemented or mounted together to minimize wave front distortion. Nonpolarizing cube beamsplitters provide a true 50/50 split at a specific laser wavelength (e.g., 632.8), regardless of the incoming polarization. These beamsplitters are particularly useful with randomly polarized lasers and are specifically designed for applications in which polarization effects must be at a minimum.
