About the Kowa BD 10X25 Green Binoculars...
Roof prism binoculars like the Kowa BD Series 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 called C coating to these Kowa Binoculars. This allows for a higher reflectivity than with silver or optically enhanced aluminum, offering a reflectance of 99% or higher across the entire visible spectrum (400 to 700 nm). Not only does this provide bright and sharp images, but accurate color reproduction is also achieved. Furthermore, the roof prism of the Schmidt prism is phase coated to prevent the loss of contrast and image resolution.
All lenses and prisms of the Kowa BD Series Binoculars are fully multicoated, ensuring a clear visual range and sharp images. This new coating technology maximizes the reflectivity of the Kowa Binocular prism and reduces the loss of light, thereby achieving brighter and sharper images.
Kowa BD Series Binoculars are ideal for observation of plants, insects, and other objects within close range. These Kowa Binoculars are very versatile!
