Предлагаемое техническое решение ставило задачу усовершенствования устройства для исследования глазного дна, содержащего систему освещений с волоконным осветительным каналом и систему наблюдения, содержащую объектив и окуляр. Между объективом и окуляром дополнительно установлена линза-коллектив на расстоянии переднего фокуса окуляра, а объектив выполнен широкоугольным с вынесенным вперед входным зрачком. Предлагаемое устройство обеспечивает возможность осмотра глазного дна под углом 140 o, что обеспечивает получение полной, вплоть до зубчатой линии, картины глазного дна в отличие от известных устройств, которые дают только фрагментарные картины глазного дна.The proposed technical solution set the task of improving the device for the study of the fundus containing a lighting system with a fiber lighting channel and a surveillance system containing a lens and an eyepiece. Between the lens and the eyepiece, a collective lens is additionally installed at the distance of the front focus of the eyepiece, and the lens is made wide-angle with the entrance pupil extended forward. The proposed device provides the ability to inspect the fundus at an angle of 140 o , which provides a complete, up to the dentate line, fundus picture, in contrast to known devices that give only fragmentary fundus pictures.
