Abstract

A projection television system (10) is provided which has a CRT (16) with a curved faceplate and a projection lens system (13) for forming an image on a screen (14). The projection lens system (13) is characterized by a power lens unit (U2) which (a) provides color correction for the lens system and (b) has two positive lens elements and a negative lens element with one of said positive lens elements (L.sub.P) being at the image side of the unit. The positive lens element (L.sub.P) at the image side of the second lens unit (U2) is preferably the strongest positive lens element in the lens system, having a focal length (f.sub.P) which is less than 1.5 times the focal length of the system (f.sub.0).
