Silverstone OCT

Silverstone RGB is the next generation of our flagship imaging platform and the most advanced retinal imaging product ever released. Silverstone RGB produces a 200° single shot retinal image of unrivaled clarity in less than ½ second and enables optomap guided SS-OCT scanning across the retina and into the far periphery. With Silverstone RGB, you don't just see the retina - you see it like never before

Silverstone RGB offers the following benefits:

  • Nine imaging modalities and UWF with integrated Swept Source OCT, facilitate detailed examination of the retina-vitreous to sclera
  • UWF guided, Swept Source OCT, images pathology anywhere on the optomap
  • 1050 nm OCT light source, provides deeper tissue penetration for clear, detailed choroidal imaging
  • 4-in-1 Color Depth ImagingTM provides important clinical data from the retinal surface through the choroid
