An optical design of a four-channel WBVR photometer based on dichroic mirrors is described. The key properties of dichroic mirrors and features of beam-splitters used are considered. Under certain conditions, the WBVR photometric system with characteristics very close to the standard system can be set up. Polarization effects in the photometer are investigated.
