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 12.7mm and 25.4mm sizes.
