The Viper HD MOA lens with embedded scale allows you to accurately determine the distance to the target. The lens is designed exclusively for the new generation of Viper HD 85 mm observation tubes.Wide field of viewThe wide-angle Viper eyepiece with 33.5 × magnification, unlike the 20-60 × version, provides a much wider field of view and, thanks to the constant magnification, the highest image resolution. The reticule applied to the optics, expressed in MOA, allows the calculation of distance correction and wind corrections .Premium class opticsThe use of selected HD glass ensures extremely high resolution , minimizes chromatic aberration, extremely faithful color reproduction and sharpness of the image from edge to edge.All glass-air surfaces are coated with premium XR anti-reflective coatings for excellent light transmission, which affects the brightness and clarity of the visible image.Moisture and dirt resistant constructionThe hard ArmorTek outer coatings protect the optics from scratches, grease and dirt.The optics are also sealed with O-rings, which prevent moisture, dust and other dirt from entering the lens. The argon filling guarantees water resistance (protection against rain and fog) and prevents internal evaporation.SPECIFICATIONSPage informationGas refill ArgonAngular field of view [°] 2.11Linear field of view at 1000 m [m] 33.5Distance from eye [mm] 18Magnification [×] 33.5DimensionsTotal length [mm] 44Weight [g] 159
