Abstract
An ophthalmologic apparatus includes: an objective lens that faces a subject's eye; an alignment light emitting unit that irradiates the subject's eye with alignment light to perform measurement of alignment between the objective lens and the subject's eye; an alignment reflection light receiving unit that receives alignment reflection light, which is a reflection of the alignment light from the subject's eye; an anterior segment camera that receives corneal reflection light; and a holder positioned between the anterior segment camera and the objective lens to hold the anterior segment camera, wherein the holder includes an imaging transmissive portion that transmits the corneal reflection light to the anterior segment camera, a first light-transmissive portion that transmits the alignment light from the alignment light emitting unit, and a second light-transmissive portion that transmits the alignment reflection light from the subject's eye.
