Abstract

The paper describes results of development of fundus-camera with non-glare optical scheme. The scheme is based on multiple lenses with a light gathering power (D/F ≤ 1) substantially less than one. Illumination of fundus can be provided through eye’s pupil less than 3 mm. And much attention was directed to method of calculation of the no-glare optical scheme. The key idea is that geometry of optic elements of the system provides that glare in the form of ghost reflection from optical surface of one element focuses on a small-size absorbing screen located on another optical surface. Shows the possibility of implementation and the experimental results. During experiments with B/W camera we got Full HD color image of fundus having the eye’s pupil diameter of 1.5 mm and illumination of fundus tissue in accordance with sanitary rules.
