ABSTRACT:
A lens adapted to image a first image plane at a reduced side onto a magnified side is provided. The lens has an optical axis. The lens includes a lens group and a concave reflective mirror. The lens group is disposed in the light path between the reduced side and the magnified side. The concave reflective mirror is disposed in the light path between the lens group and the magnified side. The offset of the first image plane with respect to the optical axis is greater than 100%. The throw ratio of the lens is less than 0.3.
