Patent ID: 8873123

Claim:
A microscope apparatus comprising: a spatial light modulator that modulates the wavefront of illuminating light from a light source; a scanner that has two mirrors independently pivoted about two non-parallel axes, and that two-dimensionally scans the illuminating light whose wavefront has been modulated by the spatial light modulator; a relay optical system that guides the illuminating light, whose traveling direction has been changed by the scanner, to an objective optical system; and a modulation-region adjusting unit that moves a wavefront modulation region of the spatial light modulator, in which an image is formed, in response to pivoting of the mirrors, wherein: a first direction is a direction in which the image of the modulation region relayed to a pupil position of the objective optical system would move when the mirrors are pivoted while the modulation region is fixed, a second direction is a direction in which the image of the modulation region relayed to the pupil position of the objective optical system would move when the mirrors are stationary while the modulation region is moved, and the modulation-region adjusting unit moves the modulation region when the mirrors are pivoted so that the second direction is opposite to the first direction, thereby keeping a position of the image of the modulation region relayed to the pupil position of the objective optical system stationary.
