Topcon TRC-NW500 Non-Mydriatic Retinal Camera

The Topcon NW500 captures enhanced quality color fundus retinal images of pupils
as small as 2mm in diameter.
Its slit scan technology produces sharp-quality images regardless of room light settings,
with more consistency, even when imaging through small pupils.

Innovative slit scan illumination and rolling shutter mechanism in the NW500
makes it possible to obtain excellent quality color fundus images
with less flare and shadow.
The slit scan technology enables consistent imaging across
the traditional three fixation positions, Disc, Center and Macula,
as well as the nine fixation positions for peripheral photography.

Compared to the conventional fundus camera, the operation
and shooting processing speed were improved with the new equipped a high-spec processor.
Capturing of both eyes can be completed within about 30 seconds.
