50/50 split ratio non-polarizing beamsplitter cubes are available in Standa! Cubes are constructed by cementing two precision right angle prisms together with metallic-dielectric coating on the hypotenuse surface. Absorption loss due to coating is around 10%, moreover these cubes do not affect polarization of the incident beam!
