FOLDED, TELECENTRIC PROJECTION LENSES FOR USE WITH PIXELIZED PANELS

摘要

Projection lenses for use with pixelized panels (PP) are provided. The projectionlenses 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 lensesare telecentric on the short conjugate side, have a large field of view in the directionof the long conjugate, and have low aberration levels, including, in particular,low levels of lateral color.
