ABSTRACT:
There is provided a compact, strong and high-performance catoptric optical system. This catoptric optical system has plural optical curved reflective surfaces. A gap between a pair of reflective surfaces, through which light incident upon said catoptric projection optical system passes, is the same gap between a pair of reflective surfaces, through which light exited from the catoptric projection optical system passes.
