Broadband polarizing cube beamsplitters provide efficient polarization for use with multiple or tunable sources. Each polarizer consists of a pair of precision right-angle prisms carefully cemented together to minimize wavefront distortion. Broadband polarizing cube beamsplitters are available in four wavelength ranges covering the visible to near infrared in 12.7 mm and 25.4 mm sizes.
