摘要：
An ophthalmologic apparatus includes a two-dimensional scanning optical system, a refractive optical system, and a concave mirror. The two-dimensional scanning optical system deflects light from a light source in a first angle range. The refractive optical system deflects the light deflected by the two-dimensional scanning optical system in a second angle range that is wider than the first angle range. The concave mirror includes a reflective surface in at least part of the rotational symmetry surface, and reflects the light emitted from the refractive optical system. The exit-side optical axis of the refractive optical system substantially coincides with the rotational symmetry axis of the rotational symmetry surface. The pupil location in the refractive optical system and the exit focus of the concave mirror are located at optically conjugate positions or in the vicinity of the positions. The exit focus is located at a subjects eye position.
