<P>PROBLEM TO BE SOLVED: To provide a fundus imaging apparatus where viewing condition of an image is adjusted by simple constitution. <P>SOLUTION: The fundus imaging apparatus for imaging the fundus of the eye to be tested and displaying an image on a monitor has: an illumination optical system having an optical member for condensing laser beams on an observation surface of the eye fundus and a scanning means for two-dimensionally scanning the eye fundus with the laser beams; an imaging optical system which shares at least a part of the illumination optical system and receiving reflected light of the laser beams reflected by the eye fundus so as to obtain the image; at least two kinds of beam restriction members restricting passage of the reflected light and removably arranged at a position in the imaging optical system which has a conjugate relationship with the beam-condensing point of the observation surface; and a switching means for switching and arranging each of at least two kinds of beam restriction members to a conjugate position. The switching means is provided with a driving means for switching the beam restriction members arranged at the conjugate position. and the driving means is used also as a driving means used for changing the opening diameter of one beam restriction member. <P>COPYRIGHT: (C)2007,JPO&INPIT |
