The 10x42 binoculars (BD42-10GR) feature phase corrected prism coating and a highly reflective aluminum coating to ensure sharp images and accurate color reproduction. The Bak4 prism gives you bright, clear images all the way to the edge of the objective lens.
All lenses and prisms are manufactured with multilayered coating, ensuring a bright and clear visual range.
The housing of these binoculars is waterproof and filled with dry nitrogen gas to prevent the lens from fogging. The binoculars can be used in the rain and other harsh weather conditions. (Not intended for underwater use)
This model has twist-up eyecups suitable for both eyeglass wearers and non-eyeglass wearers.
The binoculars feature easy focusing and a smooth turning focus wheel. Through the use of an inner focusing mechanism, the light, compact design was made possible.
The model uses 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 (400 to 700mm).
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.
