Abstract
A deformable mirror includes a first base plate having a first reference surface, a transparent second base plate having a second reference surface opposed to the first reference surface, a flexible member disposed between the first base plate and the second base plate and having a reflective surface on a surface thereof, the flexible member being adapted to be fitted on the first reference surface or on the second reference surface, and a driver for fitting the flexible member on the first reference surface or on the second reference surface, wherein the flexible member is held between the first base plate and the second base plate, and the light rays to be reflected by the reflective surface are imparted with the first degree of spherical aberration or with the second degree of spherical aberration by fitting the flexible member on the first reference surface or on the second reference surface by the driver.
