Provided is an ophthalmologic apparatus including one dichroic mirror, which is arranged eccentrically with respect to an optical axis of light from an eye to be inspected to separate the light from the eye to be inspected; another dichroic mirror, which is configured to separate light separated by the one dichroic mirror by being transmitted through the one dichroic mirror; and a positive lens, which is configured to guide the light from the eye to be inspected to the one dichroic mirror as convergent light, and to guide the light from the eye to be inspected to the another dichroic mirror as divergent light, wherein an eccentric section of the one dichroic mirror and an eccentric section of the another dichroic mirror have a positional relationship of being substantially perpendicular to each other and having substantially the same eccentric amount, to thereby correct astigmatism. |

1. An ophthalmologic apparatus, comprising:
four optical systems of a first optical system, a second optical system, a third optical system, and a fourth optical system; a first dichroic mirror, which is arranged eccentrically with respect to an optical axis of light from an eye to be inspected to separate the first optical system; a second dichroic mirror, to which the light from the eye to be inspected is guided through a positive lens, the second dichroic mirror being arranged eccentrically with respect to the optical axis of the light from the eye to be inspected to separate the third optical system; and a third dichroic mirror, which is arranged eccentrically with respect to the optical axis of the light from the eye to be inspected to separate the second optical system by reflection and to separate the fourth optical system by transmission, wherein the positive lens is configured to cause light from a fundus of the eye to be inspected to enter the second dichroic mirror as convergent light, and to cause the light from the fundus of the eye to be inspected to enter the third dichroic mirror as divergent light, and wherein an eccentric section of the second dichroic mirror and an eccentric section of the third dichroic mirror have a positional relationship of being substantially perpendicular to each other and having substantially the same eccentric amount, to thereby correct astigmatism. |
