  • Page 112: Operation Principle

    OPERATION PRINCIPLE The patient's eye is illuminated by near infrared light, which is emitted by the fundus observation illumi- nation (IR LED). The fundus observation/photography optical system forms an image on the fundus observation camera, and the image is observed on the touch display (color LC monitor). By operating the photography button, the patient's eye is illuminated by the light emitted by the fundus photography illumination (xenon lamp).
