A lens system for use with a scanning laser ophthalmoscope to produce a wide field of view includes a first lens set and a second lens set. The first lens set provides an aerial image of the fundus of an eye along an aerial image plane anterior to the first lens set. A second lens focuses laser light from a scanning laser ophthalmoscope on the aerial image, which is then refocused by the first lens set on the fundus. The second lens set also receives and provides reflected light focused at the aerial image and redirects it to the entrance pupil of the ophthalmoscope in a substantially collimated form. |
