The aspherical lens system was first used in very expensive binoculars and cameras. It wasn't used in riflescopes because it couldn't take the pounding that scopes demanded. Not anymore! Simmons has created a new aspherical lens system, just for riflescopes.

It now performs beautifully in their new, more compact 44mm scope, AETEC. It creates the widest field of view in the industry, and the edges are as bright as the center. Plus it has a longer eye relief than most conventional wide angle systems. AETEC features fully multi-coated lenses, 1/4 MOA adjustments, and is waterproof, shockproof and fogproof.
