Spectral Optics provides broadband polarizing beamsplitter cubes that are made from SF2 glasses. Thanks to the high refractive index of SF2 glass, it can make these cube beamsplitters provide a high-performance broadband polarization.

 

Due to the limitation of the material, it is applicable for low to mid power light source applications, up to 1 J/cm2.
