Navitar has leapfrogged the current dome lens optical technologies to offer a single lens dome presentation solution for customers that require higher resolution on screen. The new Navitar 6.75 mm HemiStar projection lens is designed to project a full 180 degree image onto a hemispherical dome surface in combination with a LCD or single chip DLP projector of up to 1.3” format.
