The invention provides a non-imaging condenser lens comprising a flat-shaped transparent body, a conical bulge and a plurality of ring-shaped bulges, wherein the transparent body comprises a first surface and a second surface which are oppositely arranged. The conical bulge is arranged on the first surface. The ring-shaped bulges are arranged on the first surface, surround the centre of a circle of the bottom of the conical bulge and are distributed around the conical bulge in concentric circles, and the cross sections of the ring-shaped bulges, which are vertical to the direction of the first surface, are a plurality of triangles which are adjacently arranged along the ring-shaped bulges and are distributed at both sides of the conical bulge. Light converged by the non-imaging condenser lens is distributed evenly. The invention also provides a solar condenser.
