Abstract
A projection television system includes a planar projection screen, a CRT for producing a phosphor image, and a lens assembly for focusing the phosphor image onto the projection screen. The lens assembly is arranged such that its optical axis is skewed with respect to an axis normal to the projection screen. The system further includes a correction member on which the CRT and the lens assembly are fixed so that a planar outside surface of the CRT is oriented at the Scheimpflug angle with respect to a flat rear optical surface of the lens assembly. In a preferred embodiment, the correction member is integral with rear element of the lens assembly.
