Description
Completely rethought, the design of the Vortex Viper HD line follows all the current trends in the ergonomics of spotting scopes. The larger-diameter spiral focuser delivers fast, smooth and precise focusing. The tripod mounting clamp is made using the flexible Manfrotto RC2 system, which is the current standard for professional photography and video recording. The changes captured the optical characteristics. A larger lens diameter picks up significantly more light, and, in combination with proprietary illuminating coatings, Vortex XR Plus and dielectric coatings of Plasma Tech prisms, will provide significantly I reduce visibility when being careful during the day and in the world. A low-dispersion HD lens with high density eliminates almost all optical disturbances across the entire field of view. Those who believe that a High-End class telescope is obligated to squander every penny in the world, will definitely know their mercy the first time they meet the Vortex Viper HD 20-60x85/45.
Premium HD glass lenses with high density and extra-low dispersion ensure excellent color rendering and high image separation. The fracture coefficient of low-disperse glass is slightly dependent on the light frequency (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. 
The patented premium spherical anti-glare coating of Vortex XR Plus lenses is applied to all optical surfaces that come into contact with surfaces or inert gas and allows for maximum light transmission, clarity and brightness of the image. Plasma Tech coating technology ensures unsurpassed durability and productivity of the coating.
ArmorTek superior coating will protect lenses from smudges, oils and debris. Plasma Tech coating technology ensures unsurpassed durability and productivity of the coating.
Dielectric Prism Coatings The dielectric spherical coating of the prisms will ensure the maximum value of the light output coefficient when combined with metal coatings. This significantly improves the light transmission, which ensures a clear and bright image with the most accurate color. Plasma Tech coating technology ensures unsurpassed durability and productivity of the coating.
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 inert gas, 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 argon), which does not contain water vapor in its storage and does not condense.
