The beamsplitter penta prisms consist of a precision penta prism carefully cemented together with a wedge to minimize wavefront distortion and beam skewing. The cemented surface of the wedge is coated with a multilayer beamsplitter coating tuned to the application. The three 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.
Beamsplitter penta prisms are available in unpolarized, non-polarizing and polarizing designs. The functional features of these designs are similar to the respective cube polarizers.
