These beamsplitters have minimal polarization sensitivity. Therefore they may be used in polarized optical systems.
Due to the metallic component of the hybrid coating, these beamsplitters are not intended for use with high power lasers since they show some absorption – typically about 8%. Non‑polarizing beamsplitters are less sensitive to changes in angle of incidence than pure dielectric unpolarized beamsplitters.
The beamsplitter cube consists of a pair of precision right-angle prisms carefully cemented together to minimize wavefront distortion and beam skewing. The hypotenuse of one prism is coated with a multilayer beamsplitter coating tuned to the application. The four outside surfaces of the prism are anti-reflection (AR) coated with "V" type or broadband coatings to minimize surface reflection losses over the specific wavelength range.
