Leupold Rifle Scopes
Optical Quality A scope’s optical quality is just as important as its ruggedness. Lens glass is carefully chosen based on its function within the scope and its ability to meet the optical requirements specified by optical engineers. Glass is carefully cut and polished to remove any scratches or inclusions that could interfere with the clean passage of light through the lens. Special multicoatings (layers of metallic compounds that increase light transmission) are applied to maximize light transference and clarity. The result is unsurpassed clarity and brightness, even when conditions are far from ideal. Today it is much easier to spot the difference between a tan game coat and brown underbrush than it was even a generation ago. Of course, lenses are only part of the optical equation. Glare is the enemy of light management, and it’s a difficult element to master. Extensive internal blackening of components, (including lens edges in some cutting-edge rifle scopes, coupled with intensive grooving of the inside of the scope tube itself, causes light to be channeled properly through the scope. These treatments reduce the incidence of stray light bouncing around within the scope body to ruin image quality.
