Olympus CLV-290SL Xenon Endoscopic Light Source

With the endoscopic light source CLV-290SL and its newly designed waterproof one-touch connector, pre-procedure setup has never been easier to access brighter, more powerful HDTV and NBI.




EVIS LUCERA ELITE CLV-290SL Xenon Endoscopic Light Source

One-touch access to HDTV and NBI


Main Features

  • NBI (Narrow Band Imaging) in EVIS LUCERA ELITE provides twice the viewable distance of EVIS LUCERA SPECTRUM,while advanced noise reduction works more effectively and image response speed from dark to bright is much faster.
  • The newly designed waterproof one-touch connector allows a one-step connection to the light source and does not require a scope cable.
  • Considerable reduction in operating noise thanks to redesigned fan.
  • Link connection to peripheral devices avoids complicated cable connections and accelerates transmission speed.
  • Improved AFI (Auto Fluorescence Imaging) produces less color splitting by quicker image tracking than previous models. With its high image quality and minimized noise, it enables accurate observation of mucosal conditions.
