Abstract:
An exposure apparatus includes a sensor for detecting light arriving from a projection optical system via a liquid provided on an image plane side of the projection optical system. The sensor includes a light transmissive member provided on a stage and a light receiving element for receiving light arriving from the projection optical system via the light transmissive member. The light transmissive member includes a first surface and a second surface. The first surface is arranged on the stage, comes into contact with the liquid, and is a surface on which the light arriving from the projection optical system is incident via the liquid. At least one of the first and second surfaces diffuses or diffracts the light having arrived from the projection optical system. The light receiving element receives the light that has been diffused or diffracted.

Claim (Index 11):
The exposure apparatus according to  claim 1 , wherein the sensor is configured to measure a spatial image formed by the projection optical system based on a light-receiving result of the light by the light receiving element.
