Abstract
Six-component projection lens systems ( ) for use in CRT projection televisions ( ) are provided. To provide an improved overall modulation transfer function across the field of view of the lens, the system's first lens element (L ) has an object side surface (S ) which has a best fit spherical surface which is convex to the CRT ( ). To provide partial axial color correction, the system's second lens element (L ) is made of a high dispersion material, such as styrene.
