Imaging system of fundus camera

The invention relates to the technical field of optical equipment, in particular to an imaging system of a fundus camera. Comprising a first lens, a second lens, a diaphragm, a third lens, an optical filter, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens, a tenth lens, an eleventh lens, a twelfth lens and a photosensitive component which are sequentially arranged from the object side to the image side in the optical axis direction. By reasonably distributing the focal lengths of the lenses of the imaging system, under the mutual cooperation of the lenses, the optical phase difference can be well corrected, image post-processing through software is not needed, and the fundus phase with high image quality can be obtained. 本发明涉及光学设备技术领域，尤其涉及一种眼底照相机成像系统，包括沿光轴方向由物侧至像侧依次设置的第一透镜、第二透镜、光阑、第三透镜、滤光片、第四透镜、第五透镜、第六透镜、第七透镜、第八透镜、第九透镜、第十透镜、第十一透镜、第十二透镜及感光部件。本发明通过合理分配成像系统各透镜的焦距，在各透镜的相互配合下，可很好地矫正光学相差，无需通过软件进行图像后处理，能够获得高画质的眼底相。
