Abstract: Light from a laser light source is projected on the ocular fundus of a subject eye via a scanning optical system and an objective lens optical system, and reflected light from the ocular fundus follows the opposite path and is incident on a light shielding member at which harmful reflected light from an objective lens plane is shielded. The reflected light from the ocular fundus having passed through the light shielding member is received by a light receiving element via a light receiving pinhole disposed in the vicinity of the ocular fundus conjugate position. The objective lens optical system is composed of a first lens group and a second lens group, and within a normal diopter adjustment range, an ocular fundus conjugate plane is moved in a space between the first and second lens groups so as not overlap the objective lens plane.
