Projection lenses for use with pixelized panels (PP) are provided. The
projection lenses have a first unit (U1) separated from a positive second
unit (U2) by a distance sufficient to accept a reflective surface (RS)
for folding the lens' optical axis. The lenses are telecentric on the
short conjugate side, have a large field of view in the direction of the
long conjugate, and have low aberration levels. By using negative lens
elements (L.sub.U1/N1 and L.sub.U1/N2) composed of plastic materials
having large positive Q-values at the long conjugate side of the first
lens unit (U1), the lenses can achieve low levels of lateral color,
including low levels of secondary lateral color, with reduced cost
compared to lenses which employ anomalous dispersion glasses in the first
lens unit.
