Claims10
A device for illuminating a fiber-optical system comprising
- a. two light sources having broadly directed beams, each beam having an optical axis, the light sources arranged with respect to each other such that the optical axes of the beams intersect at a cross point,
- b. two light entrances to a fiber-optical system aligned with the optical axes of the light sources each located on the opposite side of the cross point from one of the sources, and
- c. a beam splitting mirror arranged in the region of the cross point for dividing the impinging light beam from each of the light sources into two segments such that two of said segments, one from each of the two light sources, are coincident upon one of said two light entrances.
