Optical lighting system for fundus camera, has reflective optical element whose focus point of to-be-examined pupil of eye is in correspondence with focus point of another reflective optical element of perforated mirror

摘要

#CMT# #/CMT# The system has an illumination beam path which leads from an illumination source to eye (6). A perforated mirror (7) is provided for separating the two beam paths. The reflective optical elements (2,3) with curved surface are arranged such that the focus point of reflective optical element (2) of to-be-examined pupil (5) of eye (6) is in correspondence with focus point of reflective optical element (3) of perforated mirror. The spacing between the focal spots is set to 100-500 mm. #CMT#USE : #/CMT# Optical lighting system for fundus camera used in laser application. Can also be used in ophthalmologic apparatus. #CMT#ADVANTAGE : #/CMT# The aberrations of the pupil image can be reduced such that homogeneous illumination of the retina can be obtained. The generation of artifacts in the fundus image can be prevented. The structure of the optical lighting system is simple and compact. The light can be easily penetrated into the patients eye. The quality of the pupil image can be improved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an explanatory view of the optical lighting system. 1 : Imaging optics 2,3 : Reflective optical elements 5 : To-be-examined pupil 6 : Eye 7 : Perforated mirror.
