Wider Color Gamut
More Details, More Difference

The VISERA 4K UHD generates a wider color gamut by adopting the 4K color format (BT2020).
This enables rich color reproducibility and provides suitable colors for each clinical discipline.

  • Allows surgeons to observe fine patterns and structures in high precision
  • Much more subtle differences in reds and yellows than conventional HDTV
Magnified Visualization
Get Closer
  • Panoramic view for the whole OR team 
with optimal viewing distance and wide viewing angle
  • Structure enhancement processing based on image enhancement technology enables clearer recognition of human tissue and instruments in the body cavity
  • Allows surgeons to observe fine patterns and structures of tissues in the body in high precision even when enlarged
  • Equivalent to Full HD resolution even at 2.0x zoom
  • Electric zoom allows for the scope to be moved from the operating field in order to avoid mist and smoke and to reduce "sword-fighting" of hand instruments
