What is phase coating and what does it do?
By design, roof prism binoculars split the light entering the barrels into two separate paths. Although they are subsequently forced back together when they reach the viewer's eye, this results in reduced contrast and image resolution . . . sometimes referred to as "out of phase" or "phase shift." PENTAX has incorporated a thin coating on the roof prism surface in its DCF WP binoculars, which forces the light beams back into phase, thus creating enhanced contrast and a sharper view.
