- 摘要：
PROBLEM TO BE SOLVED: To provide the so-called chromatic aberration-free model eye, giving the same refractive power to different wavelengths.
SOLUTION: This model eye 60 includes: a simulated fundus for diffusing light and an optical system, which guides a light beam emitted from an ophthalmologic examination apparatus 1A as an incident light beam P1 to the simulated fundus 64, and emits diffused reflected light P2 diffused at the simulated fundus 64 as an outgoing light beam P2 giving a predetermined diopter for performing refractive power calibration toward the ophthalmologic examination apparatus. The optical system includes: a first reflector 62 having a first reflector axis O1 and a first reflecting surface and a second reflector 63 disposed between the first reflector 62 and the simulated fundus 64 and having a second reflecting surface. The incident light beam P1 from the ophthalmologic examination apparatus 1A is guided to the simulated fundus 64 through the first reflecting surface and the second reflecting surface in order, and the diffused reflected light from the simulated fundus 64 is emitted as an outgoing light beam P2 from the first reflecting surface through the second reflecting surface and the first reflecting surface in order.
