Dichroic coatings will transmit some part of the spectrum while reflecting the other part. In a cube beam splitter it is hard to achieve the non-polarization condition especially when the angle of incidence is steeper. This beam splitter coating will transmit the visible spectrum except the specified color (Red or Blue or green). All the other four sides of the cube beam splitter are coated with broadband antireflection coating.
