Description

The Kowa company has created a breakthrough in the field of sports optics. Kowa BD II XD binoculars really allow you to protect those whose optical design previously did not allow them to do so. The extra-wide field of view of binoculars is, without a doubt, the most significant achievement of Kowa engineers in the last decade. At the moment, none of the competitors are able to come close to the enemy's results, while maintaining high image clarity. Another advantage of these binoculars is the compactness and minimal moisture of their magnesium body with high image acuity, which ensures the low dispersion of the Kowa XD. All optical surfaces are highly coated, and the prisms are coated with proprietary phase-correcting and high-temperature dielectric C3 coatings for crystalline image clarity. Special coating of eyepieces and lenses Kowa KR coating reduces the risk of smudges and waterproofness. The binocular body is waterproof and filled with dry nitrogen, which prevents fogging of the optics during sudden temperature changes. The attractive, lightweight and stylish binoculars of the BD II XD series are ideal for sports and tourism, as well as for watering and outdoor observation, and with a wide field of view, they are recommended for astro enthusiasts.
Features:
Kowa XD (Extra Low Dispersion) is a special grade of optical glass with low dispersion, manufactured by Kowa for binocular lenses and spotting scopes, placing the number of crystals in fluorite - the very best Today is the day of material for the production of lenses with ultra-low dispersion. The fracture coefficient of low-disperse glass is slightly dependent on the light frequency (in the spectrum). All the light quills break by the same amount of kut. The use of cold glass in the lens design makes it possible to avoid such unpleasant aberrations as chromatism. The profitability of such a warehouse is very high, due to which only manufacturers of high-tech optics stagnate their premium-class products. Kowa confidently confirms the superiority of Kowa XD over other types of low-disperse glass, which has been repeatedly confirmed by tests and expert opinion. The lens design of this model has 2 Kowa XD lenses.
Wide Angle - All binoculars in the BDII-XD series are wide-angle binoculars and comply with the international standard ISO 14132-2 for optics and optical accessories. One of the most prominent optical features of the BDII-XD series is that it has a wide range of features that can boast the widest characteristics of its class. The look is extremely comfortable for the eye, so you can work on trivale vikoristannya in the field of satisfaction. Use a wider field of view to look for an object that is lighter and lighter, especially when panning a wide area or unfastening a loose object. In simple words, this can mean the difference between what you mark the object and what you don’t.
Branded coating of Kowa C3 prisms - Kowa binoculars, based on the ROOF scheme, have Schmidt-Pechan vicorized prisms manufactured from the BAK-4 optical glass. Since one of the surfaces of the Pechan prism does not give full reflection, Kowa has broken up the coating with the most important feature that beats - “KowaC³”. This made it possible to eliminate the coefficient of viscosity in other coatings in which silver and aluminum are tempered. Thus, KowaC coverage has a reflection coefficient of 99% or more in the entire visible region of the spectrum (from 400 to 700 nm).


Kowa Repelling (KR) Coating - A highly functional coating, specially formulated for Kowa binoculars, which can be applied to the outer sides of lenses that are prone to smudges, and are also hydrophobic and hydrophobic. The KR coating protects the lenses from any influx of water (rain, snow, fog, breezes or heavy water), as well as from the accumulation of debris from water and oils. It is enough to simply shake the binoculars vigorously after drying, and drops of water will be removed from the outer surface of the lenses. This coating has sufficient hardness and resists the appearance of sagging marks with mechanical injection of low to medium force. This allows for a vikorist approach in extreme minds and thus preserves the functionality of the optics.
Phase Coating is a special phase-regulating coating that is applied to one surface of the prism wrapping system in the form of very thin balls. The quality of such a coating is very high, and the application process requires precision precision, which is so technologically advanced that optics manufacturers can only afford it. Phase correction is also necessary for the Roof optical system; fragments passing through such a prism, the light flow is decomposed into two parallel beams of light fibers, and the phase displacement occurs by half light color, which leads to a change in the separation of the image, as well as a decrease in contrast. Phase Coating corrects this problem. As a result, the image is as clear and contrasting as possible. Today, without a phase-correcting coating, the design of a high-viscosity optical device of the Roof prism system is practically inconceivable
Fully Multi Coated (FMC) - all lenses and prisms are coated with rich spherical reflective coatings, which allows increasing the light transmission of the optical system and increasing image contrast. Kowa's lens coating technology, refined over decades, further enhances the light-transmitting power of all lenses.
Waterproof - means that the optics are sealed with a reinforced O-ring and are protected from the international class IPX7. Being enclosed in a row of 30 ridges per depth of 1 meter does not affect the least harm and does not affect its functionality. Such weather opinions are not scary.
Fogproof - means that the middle of the body is filled with dry nitrogen, which makes it difficult for moisture to condense on the internal surfaces during temperature changes. As a result, the optics do not become stained in the middle, and there is also no corrosion of materials due to the infusion of moisture. The air is removed from the device and replaced with an inert gas (in this case, nitrogen N2), which does not contain water vapor and does not condense in its storage.
Magnesium Alloy Body - Due to its small size and hardness in alloys, magnesium is vicorized in various industries with improved performance characteristics. The bodies of the binoculars, made of magnesium alloy, are currently considered to be of the highest quality and are subject to high-quality processing, which is now positively affected by the current state of the art. It looks good and pleases the eye. The optics in such housings will last as long as possible.
