Description
Kowa Genesis Prominar XD premium binoculars are manufactured in Japan to the highest standards. Their design has high-quality components and optics. Kowa Genesis Prominar XD 8x33 binoculars are equipped with 33mm lenses made from XD glass with ultra-low dispersion, a wide field of view, and a small minimum focusing distance of 1.5 m. Prisms with phase correction and C3 coatings and lenses with extra spherical coatings ensure clear, sharp images with excellent detail. The lightweight, ergonomic body of the Kowa Prominar XD 8x33 binoculars is made from magnesium alloy, equipped with a dry humum coating, waterproof and filled with dry nitrogen, which prevents fogging of the optics during sudden temperature changes.

Prominar XD (Extra Low Dispersion) is a special grade of low dispersion optical glass manufactured by Kowa for binocular lenses and spotting scopes. The fracture coefficient of low-disperse glass is slightly dependent on the light frequency (spectrum). All the light tails break by the same amount of kut. The stagnation of these glasses in the lens design makes it possible to practically avoid such unacceptable 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 Prominar XD over other types of low-dispersion glass, which has been repeatedly confirmed by tests and expert opinion
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 boasts the widest range of characteristics in its class. The look is extremely comfortable for the eye, so that you can work on trivale vikoristannya in the field of satisfaction. A wider field of vision should be used 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.
SK 15 - the next step in the development of Roof binocular prisms was the use of a special grade of optical glass SK15 with a high fracture rate. The leader in the production of optical glasses in Japan, the SUMITA company, is emerging. The preparation of combined Roof prisms from glass SK15 and BAK4 makes it possible to practically prevent parasitic internal transformations until they melt into the image. Only two optics generators, one from Kowa, equip their binoculars with such prisms
Branded coating of Kowa C3 prisms - in Kowa binoculars, behind the ROOF scheme, there are Schmidt-Pechan prisms, made from special brands of optical glass with vinyakov parameters (BAK-4 and SK-15). Since one of the surfaces of the Pechan prism does not give full reflection, Kowa has broken up the coating with a high yield - “KowaC”. This made it possible to eliminate the coefficient of viscosity in other coatings, which have vicorized wood or aluminum. In this way, KowaC³ has a coefficient of reflection of 99% or more in the entire visible region of the spectrum (from 400 to 700 nm)
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 the amount light color, which leads to a change in the separation of the image, as well as a decrease in contrast. tse usunennya. 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.
Kowa Repelling (KR) Coating is a highly functional coating, specially formulated for Kowa binoculars, which is applied to the outer sides of lenses, resists stains and is also hydrophobic. The KR coating protects the lenses from any kind of water (rain, snow, fog, breezes or heavy water), as well as from water deposited near the water. 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.
Diopter lock - the diopter lock is equipped with a blocking mechanism that prevents the diopter change.
Waterproof - means that the optics are sealed with a high-impact O-ring and are protected against penetration by water to the international class IPX7. Being enclosed in a row of 30 lengths to a depth of 1 meter does not affect the equipment of the smallest capacity and does not affect its functionality. Such options are not scary in any weather mind.
Fogproof - means that the middle of the body is filled with dry nitrogen, which prevents condensation of moisture on the internal surfaces due to temperature changes. As a result, the optics do not fog up 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 allow water vapor in its storage and does not condense.
Magnesium Alloy Body - always equal to the small size and hardness of alloys, magnesium is used in various industrial applications 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 serve as a guide for as long as possible.
Made in Japan . It is no secret that Japan has long occupied first place among the countries in the development and promotion of advanced technologies in almost all fields of science and technology. Today, the Japanese are patenting more innovative optical technologies in Galusia, having supplanted the Germans, and have previously quietly retained their leading position here. Moreover, the philosophy of putting things to work does not allow the Japanese to spoil the average product. The very modest, scarlet inscription “Made in Japan” testifies to the high level of technology and the unproven quality of the product. In other words, you take away the best from the best.
