Catadioptric imaging lens
A catadioptric imaging lens includes: a first reflecting mirror; a second reflecting mirror; and a lens group. A reflecting surface of the first reflecting mirror is a rotationally asymmetrical aspherical, with concavity on the object side within the reference and the first orthogonal plane. A reflecting surface of the second reflecting mirror is a rotationally asymmetrical aspherical, with convexity toward the first reflecting mirror within the reference and within the second orthogonal plane. A surface in the lens group closest to the second reflecting mirror is a rotationally asymmetrical aspherical, with concavity toward the second reflecting mirror within the reference plane and convexity toward the second reflecting mirror within the third orthogonal plane.
