Kowa Genesis 10x22 PROMINAR XD Binoculars

Genesis10x22 PROMINAR XD Binoculars XD Lenses: Kowa's branded XD Lenses (eXtra-low Dispersion glass which has characteristics close to fluorite crystal), when combined with a concave lens possessing special dispersion properties, reduces a very high percentage of chromatic aberration (color blur). Their performance nearly matches Kowa's flagship models which utilize fluorite crytal lenses C3 coating: Kowa's roof prism binoculars use a Schimdt-Pechan prism. One surface of the Pechan prism does not provide total reflection, so a highly reflective C3 coating has been applied. This allows for higher reflectivity than with silver or optically enhanced aluminum which offers a 99% or higher reflectance across the entire visible spectrum (400-700nm). This not only provides bright and sharp images but also accurate color reproduction. Magnesium Alloy Body: A magnesium alloy body is formed using advanced thixomolding technology. Advanced thixomolding technology provides the benefits of a high strength metal body but in a lightweight magnesium alloy structure. The durability and reliability of these binoculars can withstand the most severe conditions which provide users the greatest degree of confidence. KR coating: Kowa's KR coating protects the lenses from dirt and other foreign residue that may affix to the lenses during normal use. Even in cases where the lens is accidentally touched, fingerprints or oil can easily be removed through proper lens cleaning methods. Waterproof Structure Filled with Dry Nitrogen Gas: The housing is waterproof and filled with dry nitrogen gas which prevents internal fogging. Not intended for underwater use.
