Intended Use
The NIDEK Non-Mydriatic Auto Fundus Camera Model AFC-330 is an ophthalmic camera that is indi-
cated for use in capturing images of the retina and the anterior segment of the eye.
* When the device is used with NAVIS-EX, for which a separate operator’s manual is provided,
the functions for image review, image processing, and exporting are available. The filed
images provide information for reference purposes.

Principle
Alignment
1. Anterior eye observation
Alignment is performed while observing the anterior eye under the anterior eye illumination
LED (infrared light) on the LCD touch-screen. When proper alignment is achieved, the fun-
dus observation screen is automatically displayed.
2. Fundus observation
A bundle of light rays from the halogen lamp passes through the infrared filter and becomes
infrared light to illuminate the fundus. Alignment and focusing of the device is performed
while observing the illuminated fundus on the LCD touch-screen.
Image capture
White light from the xenon flash lamp irradiates the anterior eye and fundus. The light
reflected from those eye portions forms an image, and the image is captured by the built-in
color CCD camera for fundus image capture.
