The apparatus includes a lens supported on a lens. The method and apparatus includes means for catching a beam of light from the primary light source and compressing the beam so that it can be transmitted by a fiber optic guide, then the beam is expanded to its original dimensions so that the normal system sensor sees the source beams at its original dimension.
