Projection lenses for use with pixelized panels (PP) are provided. The
projection lenses have first and second lens units (U1,U2), with
the first lens unit having a negative power and the second lens unit having a positive
power. The first lens unit has a first lens element (L1) having a generally
meniscus shape and a second lens element (L2) having a biconcave shape when
its surface configurations are described by best fit spherical surfaces. The second
lens element (L2) has an Abbe number (vL2) which is (a) less
than or equal to 55 and (b) less than the Abbe number (VL1) of the first
lens element (L1). The second lens element (L2) also has an optical
power (L2/0.7CA) at 0.7 of the clear aperture of its short conjugate
surface which is negative and has a magnitude which is greater than the second
lens element's on-axis optical power (L2). This combination of
lens shapes, Abbe numbers, and optical powers provides higher order lateral color
correction without the need for abnormal partial dispersion glasses.
