Cube beamsplitters-Visible grade Cube beamsplitters, although more expensive than plates, have the advantages of stability, ease of mounting, equality of optical paths and absence of second-surface ghost image. This range has hybrid coatings with considerably smaller polarising effect than the common all-dielectric types.
