Patent abstract
Projection lenses for use with pixelized panels (PP) are provided. The projection lenses have a negative first unit (U1) separated from a positive second unit (U2) by a reflective surface (RS) which folds 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, including, in particular, low levels of lateral color.
