Multicoat 4 Light reflecting off lens surfaces diminishes image quality. So Leupold engineers developed Multicoat 4, our own proprietary lens coating system to keep image quality pristine. Multicoat 4 greatly increases the amount of all available light that reaches your eye, while at the same time, it minimizes the reflections of the sky on the outer eyepiece. Youll never be able to control the light, but with Leupolds Multicoat 4, you can always make the most of it. Quantum Optical System Leupold optical engineers and scientists, mechanical engineers and product line managers have developed the optical system for Leupolds newest riflescopes, including the VX-1, VX-2, VX-R and VX-6. The Quantum Optical System is a new way of thinking about optical system design and is a significant leap forward in performance. Using the rugged foundation of the legendary Vari-X series and employing state-of-the-art optical and mechanical design software and manufacturing processes, this system delivers new levels of performance in every optical category. Lead free, ecologically friendly glass compositions are used throughoutthe geometry of each lens is maximized through a combination of Ze-max design software and evaluation using Leupolds Zygo Interferometer to minimize wave front error and increase resolution. The result is razor sharp imaging across the typical light conditions experienced on any huntfrom the bright daylight of varminting to the dawn and dusk hours when big whitetails are on the move. By repositioning optical elements, employing new coatings and importantly, leaving key, time-tested mechanical aspects of the Vari-X system untouched, significant performance gains have been achieved in many other areas as well. The Quantum Optical System has greatly enhanced light transmission (up to 92% in the VX-1 system and 94% in the VX-2 system), resolution and color fidelityall while preserving the ease of use and nearly indestructible ruggedness that has been a hallmark of Leupold riflescopes for generations. 2nd Generation Argon/Krypton Waterproofing While we still waterproof other optics with bone-dry nitrogen technology pioneered by Leupold Select models feature our exclusive, proprietary Argon/Krypton gas blend. Its advantages are two fold: it nearly eliminates the effects of thermal shock, and the Argon/Krypton molecules are significantly larger than nitrogen molecules, reducing the diffusion of gases sealed inside your scope even more than our proven nitrogen technology already does. We pioneered riflescope waterproofing, and now with Argon/Krypton were exceeding the standards we set ourselves. Dual Use Outstanding accuracy, legendary ruggedness, and absolute waterproof integrity. All Leupold optics offer performance that makes them equally at home in hunting or tactical environments. Leupold Mark 4 Long Range/Tactical riflescopes are excellent choices for both long-range hunting and varminting. Likewise long-range competitive shooters and members of the Fifty Caliber Shooters Association men and women who shoot competitively at ranges of 600 yards or more rely on the accuracy and durability of these scopes. See overview of each product for more detailed information on hunting, shooting, and competition applications. One inch Maintube
