Uncover details

  • TrueView Optics: apochromatic ZEISS lenses with anti-reflex coating provide true-to-life color and high contrast images.
  • VarioLight: the integrated LED light source is accompanied by a halogen filter providing the advantages of both illumination characteristics. 
  • Continuous magnification steps – 6x, 10x, 16x, 25x, 40x – show more detailed structures for enhanced insights.

Superior optics for high-definition image quality

Larger ZEISS lenses enable a higher level of light-throughput. In combination with anti-reflex coating, they also provide a high-definition image in true-to-life color with high contrast - even in 40x magnification. Additionally, the apochromatic optimization greatly reduces chromatic and spherical aberrations in favor of visualizing structural details.  


Extensive illumination and filter options

Whether you prefer the cold-white examination light of an LED or a warm-white halogen-like illumination, the new VarioLight feature allows you seamlessly switch between the two. This allows you to gain a sharper and clearer image as well as a more natural fundus impression. Together with the integrated and optional filters and diffusor, the SL 800 can be equipped to provide complete observation of the both the anterior and posterior segment.
