Broadband Non-Polarizing Beamsplitter Cube

Shanghai Optics is a leading supplier of high-quality optical components, offering polarizing cube beamsplitters for the Visible (400-700nm), NIR (700-1100nm), and Telecom (1100-1620nm) wavelength ranges. These broadband non-polarizing cube beamsplitters feature low polarization dependence, with the split ratio for both S- and P-polarized incident light remaining within 6% of each other, thanks to an advanced metallic/dielectric hybrid coating.

Designed for precision, each beamsplitter consists of a pair of high-tolerance right-angle prisms cemented together, with a specialized coating on the hypotenuse to achieve optimal performance. The antireflection coating applied to all outer surfaces ensures maximum transmission efficiency across the specified wavelength ranges. The spectral flatness of these beamsplitters minimizes any effects caused by varying angles of incidence or the use of converging or diverging beams, making them ideal for a variety of laser applications.
