Non-Mydriatic Retinal Camera

NW500

Introducing Topcon's next-generation fundus imaging camera that offers bright and sharp images in well-lit conditions, even for eyes with small pupils.*

NW500

Key features

  • Sharp, high-quality images
  • Small pupils, 2mm or larger*
  • Easy to use
  • Robotic
Features

Excellent quality fundus image
Capable of capturing fundus images through a pupil diameter as small as 2.0mm*, it provides sharp, detailed colour fundus images in dark and brightly lit rooms2.

Ease of use
Alignment, focusing, shooting, and movement between the right and left eye are operated automatically with a single touch, making the NW500 easy to operate4.

Introducing New Slit-Scan Photography

Innovative slit-scan illumination and rolling shutter mechanism in the NW500 produces excellent quality colour fundus images with less flare and shadow3

The slit-scan mechanism helps to overcome one of the known causes of poorly graded images with its ability to effectively image through small pupils. This innovative technology also helps the NW500 capture sharp, high-quality fundus images, regardless of miosis and the lighting conditions, unlike conventional fundus cameras.

In peripheral photography mode, it is possible to create a wide panorama image with an approximately 90-degree angle of view (approx. 132.3 degrees at the spherical centre of the eye3).
