A Leupold® exclusive, this system has nearly perfected Leupold’s already impeccable light management. Leupold engineers specify different coating materials for each lens surface in the riflescope, based on the lens’ index of refraction, placement and function, layering each coating to eliminate reflections and maximize light transmission. The result is unparalleled brightness and extremely sharp resolution across the entire visual field.
So the Anti Reflectoin coating on each lens is matched to each lens specifically.
