Uncover details

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

Superior optics for high-definition image quality

True-to-life color even in 40x super magnification

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

Extensive illumination and filter options

With the VarioLight feature, you can now select your preferred examination light – cold-white or warm-white. 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, you are equipped with an all-around setup for the observation of anterior and posterior segment.1

Extensive illumination and filter options

VarioLight cold-white

A slight bluish illumination benefits scattering and helps to identify irregularities within the anterior segment.

VarioLight warm-white

The warm halogen-like color temperature supports a more natural fundus impression.

Green filter (“red free“)

The redesigned filter characteristics provide a red-free, high-contrast image to improve the visualization of blood vessels.

Blue filter

In combination with the optional yellow filter, it provides enhanced contrast during fluorescence analysis.

Red filter

For differentiated observation of the retinal layers.

Enhance your focus. Innovative operator concept.

  • With AutoView control, you can easily change magnification with the motorized two-button mechanism next to the joystick.
  • The QuickStop electronic brake activates with no need to release the joystick.
  • The intelligent stand-by EcoMode saves energy by shutting down automatically when not in use.
