A catadioptric projection optical for forming an image of the intermediate
image onto a second object, the catadioptric projection optical system
include, a first dioptric group including a first lens group that has a
positive refractive power and a second lens group that has a positive
refractive power, a catadioptric group including a concave mirror and a
third lens group that an incidence light and reflected light from the
concave mirror pass, and a second dioptric group. A first deflective
reflector is arranged between the first lens group and the second lens
group. A second deflective reflector is arranged between the second lens
group and the third lens group or between the third lens group and the
second dioptric group. A first intermediate image is formed between the
second lens group and the concave mirror. A second intermediate image is
formed between the concave mirror and the second dioptric group.
