What is ED glass?

Some of Osprey Global's newest rifle scopes and optics have what is called ED glass and many customers have wondered what exactly is it? 

What Is ED Glass?

ED stands for Extra Low Dispersion and is one of the many factors that will result in increased clarity inside of a scope, pair of binoculars, spotting scope or any other product that uses magnified optics.

ED glass helps reduce chromatic aberration, which can otherwise appear as color fringing or blurriness around high-contrast edges in the sight picture.

ED glass contains rare earth compounds and are thus more expensive to manufacture. That is one reason why Osprey Global reserves this type of glass for our top of the line Elite series scopes and optics.

Why ED Glass Matters in a Rifle Scope

ED glass also increases clarity during low lighting conditions such as at dawn and dusk, resulting in an unparalleled lighting experience.
