Light reflecting off lens surfaces diminishes image quality. So Leupold engineers developed Multicoat 4, their 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. You'll never be able to control the light, but with Leupold's Multicoat 4, you can always make the most of it.
2nd Generation Argon/Krypton Waterproofing
While we still waterproof other optics with bone dry nitrogen, technology pioneered by Leupold. Select models feature their 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. Leupold pioneered riflescope waterproofing, and now with Argon/Krypton they're exceeding the standards we set ourselves.
