Abstract
In a device for supplying light to endoscopes, in particular video endscopes, the light is passed from a light source by way of a revolving filter plate with areas of primary colors, and a runner wheel, to a photoconductor of the endoscope, for illuminating an object to be examined, the colored image of which is passed to the video endoscope. The runner wheel rotates faster than the filter plate so that the beam of light on passing each transition from one colored area of the filter plate to another is covered by an opaque region of the runner wheel.
