An apparatus is provided for illuminating a fiber optic cable. A light source projects an illuminating light beam through a cold mirror placed at approximately a 45°angle to the direction of the light beam, whereby a visible component of the light beam is reflected in a direction normal to the light beam while a heat component of the light beam is passed through the cold mirror. A heat sink absorbs the heat component of the light beam. A ventilation duct at the heat sink is also included to conduct convective heat away from the apparatus. A plano-convex lens focuses the light beam at a focal point in space. A conduit support is included to support the fiber optic cable in a position incident to the light beam. The support has a cone-shaped aperture positioned coaxially with a diverging cone of the light beam from the focal point, and receives the diverging cone therein such that the conduit, coaxially inserted into the cone-shaped aperture, accommodates the total diverging cone of the light beam thereon. A heat shield is positioned in the path of the light beam, the shield having an aperture for passing the light beam therethrough while absorbing heat therein. A variable bandpass filter is positioned at the focal point of the light beam for passing a specific color of light therethrough, and includes a plurality of discrete filter elements and a motor for positioning any of the elements in the path of the light beam. A variable density filter is positioned in the path of the light beam for controlling the amount of light passing therethrough to the conduit.

An illumination apparatus, comprising: a light source for projecting an illuminating light beam, the light beam having broadband energy components including a heat component; means for rejecting the heat component of the light beam; means for focusing the light beam so that the beam passes through a point in space forming a diverging cone therefrom; a conduit to receive the diverging cone for conducting the light beam; means for supporting the conduit in a position incident to the light beam, the support means having a cone-shaped aperture, the aperture positioned coaxially with the diverging cone of the light beam such that the cone of the light beam is coincident with the cone-shaped aperture in direct congruence such that the conduit, coaxially inserted into the cone-shaped aperture, receives the total diverging cone of the light beam thereon.
