OLYMPUS CLV-190

Olympus CLV-190 - EVIS EXERA III Video Xenon Light Source

The CLV-190 is a xenon light source from the Olympus EVIS EXERA III series, offering one-touch access to HDTV and Narrow Band Imaging (NBI).

Main features

• NBI observation with EVIS EXERA III 190 Series scopes gives twice the viewable distance and a brighter image, thanks to an improved lamp design and signal processing.
• A waterproof one-touch connector allows a one-step connection to the light source without a separate scope cable.
• A redesigned fan reduces operating noise.
• Link connection to peripheral devices simplifies cabling and speeds up data transmission.
• Automatic light adjustment sets the ideal illumination level for each scope.

Illumination

The CLV-190 uses a 300 W ozone-free xenon short-arc lamp with an average life of approximately 500 hours of continuous use, ignited via a switching regulator. Brightness is controlled by a light-path diaphragm, with normal and high intensity modes and forced-air cooling. NBI observation is available, and color conversion can be done with a special-purpose filter. A 12 V, 35 W halogen emergency lamp (average life approximately 500 hours) is built into the mirror as backup illumination.

Automatic brightness adjustment

A servo-diaphragm method adjusts brightness automatically across 17 steps of automatic exposure.

Air and water feeding

A diaphragm-type pump supplies air at four pressure levels (off, low, medium, high). Water is fed by pressurizing a detachable water container with air.

Front panel indicators and memory

Front panel indicators show the status of the emergency lamp (absence, disconnection, or use) and light up when NBI observation is enabled. Settings are stored even when the light source is switched off, except for the filter setting.
