Olympus EVIS EXERA III CLV-190 Xenon Light Source

At-a-glance (compact 8–12 lines)

The Olympus EVIS EXERA III CLV-190 is a 300 W xenon (ozone-free) light source built for EVIS EXERA III endoscopy systems.
It’s designed to make setup faster with a waterproof one-touch connector—enabling one-step scope connection to the light source and removing the need for a separate video cable connection to the video processor.
For image-enhanced exams, Narrow Band Imaging (NBI) is supported, with Olympus noting significantly increased brightness and up to twice the viewable distance in the lumen due to improved lamp design and signal processing.
A redesigned cooling fan helps reduce operating noise compared to previous generations.
Published specs include 100–240 VAC, 600 VA power consumption, and a 19 kg chassis.

Key benefits (why teams choose the CLV-190)

Brighter NBI performance for enhanced visualization

• NBI observation available on the CLV-190 platform.

• Olympus notes significantly increased NBI brightness and up to 2× viewable distance in the lumen with EVIS EXERA III.

Faster setup and simpler cabling

• Waterproof one-touch connector supports quick connection and eliminates the need for a separate video cable connection to the processor.

• Link connection to peripheral devices (e.g., ScopeGuide or flushing pumps) helps avoid complicated cabling and accelerates transmission speed.

• A redesigned cooling fan helps reduce operating noise compared to prior generations.
