- 摘要：
PROBLEM TO BE SOLVED: To reduce distortion by an aberration and the reflection of noise light when photographing the fundus images of a large photographing field angle by mounting a wide angle lens attachment.
SOLUTION: The scanning laser ophthalmoscope comprises an irradiation optical system for irradiating the fundus of an eye to be examined with a laser beam emitted from a laser light source, a scanning means for two-dimensionally scanning the laser beam emitted from the laser light source on the fundus and a light receiving optical system for receiving the laser beam with which the fundus of the eye to be examined is irradiated in a photodetector and photographs the fundus image of the eye to be examined. The scanning laser ophthalmoscope is provided with the wide angle lens attachment which can be mounted near the inspection window of the ophthalmoscope in order to widen the photographing field angle of the fundus image, is provided with a wide angle lens system composed by serially arranging at least two convex meniscus lenses turning the concave surface side to the side of the eye to be examined, and is arranged in the state of inclining the wide angle lens system to the photographing optical axis of the ophthalmoscope.
