Abstract
A catadioptric system (LS) is provided with: a first reflecting mirror (M1) that reflects light from an object; a second reflecting mirror (M2) that reflects light reflected by the first reflecting mirror (M1); a first lens group (G1) that transmits light reflected by the first reflecting mirror (41) and travelling toward the second reflecting mirror (M2), and transmits light reflected by the second reflecting mirror (M2); and a second lens group (G2) that transmits light reflected by the second reflecting mirror (M2) and transmitted through the first lens group (G1). The catadioptric system is configured that an image of the object is formed by light transmitted through the second lens group (G2).
