    摘要: A cataoptric projection optical system for projecting a pattern on an object surface onto an image surface and for serving as an imaging system that forms an intermediate image includes first, second, third and fourth mirrors serving substantially as a coaxial system so as to sequentially reflect light from an object side to an image side, and being arranged so that light from the object surface to the first mirror may intersect light from the second mirror to the third mirror.
