Kowa's roof prism binoculars use the schmidt-Pechan prism. One surface of the Pechan prism does not provide total reflection, so we have applied a highly reflective multi-coating of dielectrics (C3 Coating). This allows for a much higher reflectivity than with coatings of silver or optically-enhanced aluminum, offering a reflectance of 99% or higher across the entire visible spectrum. Not only does this provide bright and sharp images, but accurate color reproduction is also achieved. Furthermore, the roof surface of the Schmidt prism is phase coated (phase correction coated) to prevent the loss of contrast and image resolution.
