SYSTEM DESCRIPTION
The ELSV-24 Light Source provides high quality, white light for industrial borescope
and fiberscope inspections. It incorporates a patented and field-proven lamp
technology that has much greater efficiency than halogen or xenon lamps when
transferring light into a small fiber bundle, such as that found in borescopes and
fiberscopes. This greater efficiency allows the lamp to run at only 24W, which then
enables a small and lightweight light source design. You will also notice that the
ELSV-24 housing never gets very hot, so it is favored from a safety perspective as well.
For user convenience, the ELSV-24 is equipped with a video channel and multi-standard
light guide turret. The special video connector makes camera set-up and operation
easy by accepting the single power-video cable that is included with our BCAM
1000 c-mount borescope camera. This cable provides power to the camera and
carries the video signal from the camera back to the light source. The light source
has a video output on the back which can then be connected to a monitor or VCR
for image display and/or recording. The multi-standard light guide turret makes the
light source compatible with the four most common light guide fittings: ACMI, Wolf,
Olympus and Storz.
