Topcon TRC NW-200

Infrared light is emitted from the observation illumination optical system. By using this infrared light, the eye ground of the patient is illuminated. The image received by the built-in observation CCD camera is shown on the monitor and the inspector can observe the eye ground. After adjusting the photography position and focus, a visible light is emitted from the photography illumination optical system by operating the photography switch of the instrument body. The image received by the photography CCD camera is recorded in the memory card, a commercial computer and an external recording device. When digital zoom is set, the illumination aperture is automatically changed and the photographed corneal diameter is changed. While the infrared filter is removed from the observation illumination optical system, color photography is possible.
