The lamp is mounted in a housing which provides both shielding of the lamp to prevent stray light and heat sinking to protect the operator. Under the lamp housing is a micrometer-driven aperture controls the amount of light entering the sphere. The flux field at the exit port of the sphere is highly uniform and independent of the field of view. The exit port is approximately 45mm in diameter, and comes with a cover to avoid contamination of the coating when not in use.
