摘要:
A measurement method for measuring a wavefront aberration of a target optical system using a measurement apparatus that measures the wavefront aberration of the target optical system by detecting an interference pattern includes the steps of measuring as a system parameter a shift from a design value of a value that defines a structure of the measurement apparatus and the target optical system, and measuring the wavefront aberration of the target optical system using the system parameter.
