eyecups suitable for both eyeglass wearers and non-eyeglass wearers. Long
Eye-Relief design.
Inner Focusing Mechanism
Easy focusing and a smooth turning focus wheel.
Through the use of an inner focusing mechanism, the light, compact design
of the BD42 was made possible.
C³ Coating
Kowa's roof prism binoculars use the schmidt-Pechan
prism. One surface of 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 (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 phrase
coated (phase correction coated)to prevent the loss of contrast and image
resolution.
