PURPOSE OF USE
To observe and photograph the fundus through the pupil and document it.
OPERATION PRINCIPLE
The fundus of the patient's eye is illuminated by the infrared light emitted from the illumination
optical system. The observation CCD camera built into the instrument receives the image and
the image is indicated on the color LCD monitor allowing the operator to observe the fundus.
After adjusting the photography position and focus, the visible light is emitted from the illumina-
tion optical system provided for photography by operating the photography switch of the instru-
ment. The digital camera, which is connected to the instrument, receives the image and then
the image is recorded in the memory card built into the digital camera or the connected image
filing system or external recording device, which is a commercial product.
The fundus of the patient's eye can also be illuminated, observed and photographed by the vis-
ible light after removing the IR filter from the illumination optical system. Moreover, it is possi-
ble to perform red-free observation and photography by inserting the RF filter into the
illumination optical system.
