Technical Examples
  1. 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). The lenses are telecentric on the short conjugate side, have a large field of view in the direction of the long conjugate, have low aberration levels, and include a space between two of the lens elements making up the lens which is sufficient to accept a reflective surface (RS) for folding the lens' optical axis. The second or rear lens unit (U2) includes at least a first color-correcting lens subunit (SU2/CC1) which has a positive-followed-by-negative form and contributes to the correction of the chromatic aberrations of the projection lens, including the correction of lateral color.
