Abstract
A deformable mirror for reflecting a light beam incident thereon of the present invention includes: a flexible member which has a reflective surface and is flexibly deformable; a substrate having a reference surface which faces the flexible member; and a driving section for making the flexible member adhere to the reference surface of the substrate, thereby deforming the reflective surface of the flexible member to correspond to the reference surface. The shape of the reference surface is designed in such a manner that the light beam is provided with a spherical aberration when the reflective surface adheres to the reference surface.
