A ceramic heat shield tube telescopically surrounds at least a portion of the camera, and preferably the portion of the camera housing tube which contains the camera. The exterior surface of the camera housing tube is plated and polished to provide a highly reflective surface. The ceramic heat shield is spaced in position around the camera housing tube by a plurality of spacers projecting outwardly form the outer surface of the camera housing tube. A liquid coolant jacket may also be formed on radially opposite sides of the camera housing tube.
