The cube beamsplitter prisms produced by Ming Yuan Optoelectronics are primarily non-polarizing cube prisms, manufactured by bonding two right-angle prisms. One of the right-angle prisms is coated with a dielectric beamsplitting film layer. When light is incident perpendicular to the surface, light within 400-650nm is transmitted, while light within 700-1100nm is reflected.
