Description
These binoculars offer high optical performance, including bright and clear images, high separation and high contrast. The stench is simple in vikoristan and is ideal for guarding in open air. High-acidity models are ideal for beginners and advanced homeowners who want to enjoy clear, precise colors and contrast to the natural light. The lens for binoculars with a large 56 mm lens – BDXD is lightweight and compact, and is ideal for shooting in low light conditions without compromising image clarity. XD lenses and a wide field of view provide clear images without chromatic aberration. A rich ball coating is applied to all lenses and prism surfaces to ensure a bright and clear field of view. Robot with close focus Vinyatkov on all models. The durable, waterproof casing made of magnesium alloy, filled with nitrogen, provides binoculars for the brightest minds of Dowkill. The large, bright 56mm lens will further enhance light penetration, ensuring superior performance in low light conditions.
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 (in the spectrum). All the light quills 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-disperse glass, which has been repeatedly confirmed by tests and expert opinion.
The large 56mm lens has amazing light-gathering power, making it ideal for keeping an eye on low-light conditions without sacrificing image brightness. All optics are richly spherical coated with a variety of folding technologies, enhanced by the rich strength of Kowa optical engineering. The image is clear, bright, and retains a natural warm color.
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. The fragments of one of the surfaces of the Pechan prism do not give a full image, Kowa
has developed a dielectric cover with a high production value, which beats - "KowaC³". This made it possible to eliminate the coefficient of performance in other coatings such as wood or aluminum. Thus, KowaC coating has a reflection coefficient 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. 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.
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 ripples 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.
Waterproof - means that the optics are sealed with a reinforced O-ring and are protected from the international IPX7 class. 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 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 vase and hardness in alloys, magnesium is vicorized in various industries with improved performance characteristics. The bodies of 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 matched to the current It looks good and pleases the eye. The optics in such housings will serve as a guide for as long as possible.
