Product Information

Silverstone, The Most Powerful Tool Yet For Examining The Retina, Is The Only Ultra-widefield Imaging Device With Integrated Swept Source OCT.  Silverstone Produces A 200° Single-capture Retinal Image Of Unrivaled Clarity In Less Than ½ Second And Enables Optomap Guided OCT Scanning Across The Retina And Into The Far Periphery.  

Product Description

Silverstone, the most powerful tool yet for examining the retina, is the only ultra-widefield imaging device with integrated swept source OCT.  Silverstone produces a 200° single-capture retinal image of unrivaled clarity in less than ½ second and enables optomap guided OCT scanning across the retina and into the far periphery.  
 
Silverstone offers the following benefits:
 
  • UWF with integrated swept-source OCT, facilitates 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
  • 3-in-1 Color Depth ImagingTM provides important clinical data from the retinal surface through the choroid
