Topcon TRC-NW500 Non-Mydriatic Retinal Camera

Brand: Topcon


The Topcon NW500 is a user-friendly, robotic fundus camera that provides sharp-quality, consistent imaging even in ambient light.

Read full product description



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.
