ophthalmological refractometer

摘要

An ophthalmological refractometer comprises combined by polarization light diffuser light channel with a light source and optical system for forming microstains light on the retina and photodetectors channel with lens and optical system that forms an image of the illuminated areas of the retina to light-sensitive surface of the sensor image. Additionally, the system contains Badal system and variolense located between light diffuser and patient’s eye. The variolense is placed in a plane optically conjugated by Badals system with eye pupil plane, and the lens is located between light diffuser and photodetector.
