Abstract
An optical mixing/demixing device is provided comprising a series of solid, light transmitting blocks, each having opposed, front and rear parallel, planar faces, coated with optical interference multilayer coatings, and first and second light transmitting faces arranged one on each side of the front planar face. The blocks are packed side by side with a precision, light expanding and collimating lens on the first light transmitting face and further, similar precision lenses on each of the second light transmitting faces. The first and second light transmitting faces may also be coated with optical interference multilayer coatings that are pass band filters.
