摘要：
The utility model refers to the field of ophthalmology, specifically to optical devices for examining the fundus and can be used to detect age-related macular degeneration of the retina (AMD), including in early preclinical stages of the disease, when clinical signs of the disease do not yet appear. The device includes a lighting unit for exciting the AF of the fundus, an ocular lens (objective) a beamsplitter representing the block, and further comprising a spectral image registration unit for simultaneously recording autofluorescence images of the fundus in two spectral ranges, including a dichroic beam splitter and two image sensors for independent simultaneous detection of signals in different spectral ranges. Excitation of autofluorescence is carried out in the spectral range of 480-520 nm, and the detection of signals is carried out in the spectral ranges of 530-580 nm and 600-650 nm. The device is simple to manufacture, available for mass production and use in screening examinations of patients, for example, during the prophylactic medical examination of the population. The device allows for examination in a patient-friendly mode, which assumes a single millisecond (duration from 1 ms to 200 ms) pulsed light exposure to the eye. 2 z.p. f-ly, 2 ill. in the course of prophylactic medical examination of the population.
