Fundus Imager

The camera's optical system of the fundus imager consists of an illumination system and an imaging system. The illumination system is equipped with a fixation light source, visible illumination light source, and near-infrared focusing light source. Focusing with near-infrared light sources can be performed without pharmacologically dilating the eye. The imaging system is equipped with a focusing lens and provides a refractive compensation function of±20D.
