Kowa C3 Coating (for Kowa 10x42 BD42-10GR Green Body Binoculars): Kowa Binoculars new C3 coating technology further enhances brightness and color reproduction. Kowa Roof Prism Binoculars use the Schmidt-Pechan prisms. One surface of Pechan prism does not provide total reflection, so Kowa 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 (400 to 700nm). 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.
