Abstract
A method and apparatus which can couple a high intensity point source, such as from a single fiber, to a fiber bundle. A bundle of fibers is fed though a hole in the light post. A removable potting compound is applied to the tip of the bundle to hold the fibers together for polishing. The tip of the bundle is polished and then the potting compound is removed from the tip of the bundle. A window is placed over a light inlet of the hole so as to seal the bundle. A point source cable introduces a point source of light to the bundle of fibers. A ferrule is provided around the point source cable, having a diameter sized corresponding to a diameter of said light post. The ferrule and the bundle of fibers are clamped with a split sleeve which extends therebetween.
