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. 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 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 we’re exceeding
the standards we set ourselves.
