PROBLEM TO BE SOLVED: To provide a technique capable of inhibiting deterioration in detection accuracy of fundus oculi information caused by an adjustment of a diopter scale in a scanning laser ophthalmoscope (SLO).SOLUTION: A funduscopic apparatus comprises: an objective lens 123 a light source 101 of laser light a diopter adjusting mechanism 117 that adjusts the laser light so as to be applied onto a fundus oculi 201 as a substantial point image a fundus oculi reflection light detection unit 112 that acquires information of the fundus oculi 201 on the basis of the reflection light of the laser light from the fundus oculi 201 and an ultralow refractive index film on a transmissive optical surface of the objective lens. With the adjustment by the diopter adjusting mechanism 117, a position × conjugate with the fundus oculi may be overlapped with the objective lens or move to a near-field region.COPYRIGHT: (C)2014,JPO&INPIT【課題】本発明は、走査型レーザー検眼鏡(SLO)における視度の調整に伴う眼底情報の検出精度の低下を抑える技術を提供することを目的とする。【解決手段】対物レンズ123と、レーザー光の光源101と、レーザー光を眼底201上に略点像として照射するように調整する視度調整機構117と、レーザー光の眼底201からの反射光に基づいて、眼底201の情報を得る眼底反射光検出部112と、視度調整機構117による調整に伴い、眼底201と共役な位置×が、対物レンズ123と重複または近傍範囲に移動し得るものであり、対物レンズ123の透過光学面に超低屈折率膜が設けられている。【選択図】図1
