An ophthalmologic apparatus comprising a two dimensional scanning optical system 20, a refractive optical system 30, and a concave mirror 40. The two-dimensional system 20 deflects light from a light source 11 in a first angle range; the deflected light is deflected by the refractive system 30 in a second angle range that is wider than the first angle range. The concave mirror 40 includes a reflective surface in at least part of the rotational symmetry surface and reflects light emitted from the refractive system 30. The exit-side optical axis K of the refractive system 30 substantially coincides with the rotational symmetry axis C of the rotational symmetry surface. The pupil location F1 in the refractive system 30 and the exit focus of the concave mirror F2, are located at optically conjugate positions, or in the vicinity of the positions. The exit focus is located at a subject's eye position. Refractive system 30 may comprise first meniscus lens 31 positioned optically closest to mirror 40 and second meniscus lens 34 positioned optically closest to the two-dimensional system 20, with the second lens 34 movable in an optical axis direction of the refractive system 30, described as enabling diopter scale correction. |
