Olympus Evis Exera III CLV-190 Features

The Olympus Evis Exera III CLV-190 Xenon light source features a new connector to allow a one-step connection for the Evis Exera III endoscopes. This removes the need for a video cable connection to the video processor. It has a new cooling fan that significantly reduces the operating noise level compared to previous generations. Narrow Band Imaging (NBI) delivers significantly increased brightness as well as twice the viewable distance in the lumen with an improved lamp design and signal processing.

  • Brighter, more powerful imaging: Narrow Band Imaging (NBI) delivers twice the viewable distance.
  • Easier connection and faster transmission speed: The new waterproof connector design allows a one-step connection to the light source.
  • Automatic light adjustment to achieve the ideal illumination for observation with each scope.
