Kowa Genesis XD44 8.5X44 Binocular
Kowa Genesis XD44 8.5x DCF Binocular
Seeking a world of binoculars without chromatic aberration. Flagship model incorporating XD lenses.
The Genesis Series incorporates Kowa’s “PROMINAR” lenses. To attain the highest pinnacle of binocular performance, a total of 4 XD lenses (2 sets of 2 lenses) are utilized in the objective end of the binoculars.
This significantly reduces chromatic aberration and provides high contrast in the field of view.
The prism system of the Genesis/XD44 delivers a wide field of view and edge to edge sharpness with minimal loss of light. This high refractive roof prism (Bak4 + SK15) offers near total reflectance and when combined with Kowa’s proprietary C3 coating, delivers the clearest and sharpest image.
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).
Kowa’s roof prism binoculars use a Schmidt-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
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.
Phase coated roof prism ‒ The Schmidt prism roof surface is phase corrected to ensure sharp images and outstanding contrast.
Multi-coated Optical System provides precise color definition for a brighter and sharper image.
Waterproof structure filled with WP dry nitrogen gas
The housing is waterproof and filled with nitrogen gas which prevents internal fogging.
**Not intended for underwater use.
Twist-up multi-step eyecups allow easy viewing even when wearing eyeglasses.
