Description

Product Description Extra-Low Dispersion (ED) objective lenses provide high resolution, high contrast images virtually free of optical defects like chromatic aberration (color fringing). BaK-4 prisms increase contrast and resolution for sharper more detailed images. SMC Coating( super-multi coating) Feature: Extra-Low Dispersion ED Glass reduces chromatic aberration which causes color fringing and produces a cleaner and brighter image than standard binoculars High quality Magnesium alloy body Fully 10x magnification power, 42mm objective lens diameter, 326ft/1000yds Premium coatings provide a high light transmittance across the entire visible light spectrum, guarantee a bright, sharp image even in twilight conditions by maximizing transmission of fading light 100% waterproof through nitrogen-filled internals to handle the most extreme weather conditions, ensuring you can watch uninterrupted views SVBONY SV202 10x42 ED GLASS Binocular ED Glass ED(Extra-low Dispersion) glass is built in SV202 Binocular. ED glass has this unique characteristic and when combined with other glasses minimizes the effects of the secondary spectrum. Comparing to achromatic lenses, and ED glass reduces chromatic aberration to a remarkable degree. So if you would like to observe in low light conditions, such as at dawn or dusk and it is better to use an ED glass Binocular. 21MM Eyepiece High Index Bak4 Prisms BAK4 has a high refractive index and lower critical angle than other materials, which means it transmits light better with less light being lost due to internal reflection such as from internal bubbles trapped during the manufacturing process. Fully Multi-coated Glass Fully Multi-coated Glass means multiple coatings on all lens surfaces. And all air-to-glass surfaces are anti-reflective multi-layer coated. Fully multi-coated lenses are typical of high-end optics. High Quality Magnesium Alloy Body his SV202 binocular is of low density (about 1.8g/cm3 magnesium alloy, high impact load capacity and high quality magnesium alloy body. So you don't have to worry about breaking it outdoors. Twist-Up Eyecups Whether you wear glasses or not, you can find the comfortable observation position by adjusting the eyecups. Diopter Adjustment The diopter adjustment is a control knob on your binocular. It is designed to let you compensate for differences between your own two eyes. Once you set the diopter, then the two barrels should stay in proper relation. From then on you can focus just by turning the central focusing knob. Water Proofing 100% waterproof internals to handle the most extreme weather conditions, ensuring you can watch uninterrupted views. about svbony
