Abstract
An apparatus is provided for curing a coating applied to an optical fiber. An elongated ultraviolet lamp and the optical fiber emerging from the coater are located at focii of an elliptical mirror which focuses the ultraviolet energy onto the coated fiber. The fiber is surrounded by a cylindrical chamber that is transparent to ultraviolet light. The chamber includes a jacket through which there flows a fluid which absorbs infrared energy. A cooling gas flows from a annular slot located at the bottom end of the chamber. The slot is so angled that gas flowing therefrom is directed upwardly and inwardly toward the coated fiber so that there exists within the chamber a recirculating flow of cooling gas. This enables the cooling gas to repeatedly absorb heat from the coated fiber and give up that heat to the chamber wall which is cooled by the fluid.
