Abstract
A deformable mirror including: a flexible member including a reflective surface for reflecting light incident thereupon; and a reference surface substrate including a support portion for supporting a peripheral portion of the flexible member, and a curved portion provided inside the support portion, the curved portion providing a space for allowing for the flexible member to be elastically deformed. A height of a central portion of the curved portion of the reference surface substrate is set to be equal to or less than a height of the support portion of the reference surface substrate. The flexible member is elastically deformed by being drawn toward the curved portion of the reference surface substrate, thereby giving a predetermined aberration to light incident upon the reflective surface of the flexible member.
