Light Sources, Light Leads, and Camera Systems



Good quality light is essential to optimize endoscopic examination, but light can also be used therapeutically. Imaging, down an endoscope, depends upon effective transmission of light from the light source, through a light cable and the endoscope’s intrinsic light guide. The image is viewed via an optical system, usually to a camera at the eyepiece, and displayed on a monitor or via a tip-mounted camera directly to the monitor.
