    • An exposure apparatus and manufacturing method of device are provided to prevent excessive degradation of measuring accuracy by including a projection optical system. An exposure apparatus includes an illumination optical system(IL), a round stage(RS), a projection optical system(PO), a wafer stage(WS), an measuring system(M), and a controller(CNT). The illumination optical system changes a lighting condition. The round stage maintains the round. The wafer stage maintains the wafer. A pattern of the round stage is projected on a target substrate through the projection optical system by illuminating a corresponding round stage using the illumination optical system. The measuring system performs an exposure control measurement using a first mark arranged on the round stage and a second mark arranged on the wafer stage. The controller sets up an illumination condition different from a predetermined illumination condition.

    • An exposure apparatus is provided to precisely measure the wave front aberration of a projection optical system by including a projection optical system for projecting the pattern of a reticle to a substrate. An interferometer measures the wave front of the light passing through a projection optical system(5) in first and second directions. A focal position detecting unit respectively detects the focal positions of the projection optical system in the first and second directions. A calculation unit calculates the wave front aberration of the projection optical system based upon the measurement result of the interferometer and the detection result of the focal position detecting unit. The calculation unit calculates astigmatism of the projection optical system based upon the detection result of the focal position detecting unit.
