ABSTRACT:
A compact optical system capable of providing a clear image of minimal distortion even at a wide field angle. The optical system is a decentered optical system (10). Curved surfaces (3 and 4) constituting the optical system include at least one rotationally asymmetric surface having no axis of rotational symmetry in nor out of the surface. To correct rotationally asymmetric aberrations due to decentration by the rotationally asymmetric surface, the following condition is satisfied:
