Abstract
An electrically energizable high intensity, radiant energy heater (8) having a general M-shape for providing a pocket (20) for localized high intensity isothermal heating for fusion and fiber processing. The heater is shaped to provide easy access for a fiber (18) at an entry (16) to enable insertion of the fiber into the isothermal high temperature zone in pocket (20). A second re-entrant wall external to the pocket provides radiant shielding and buffers the isothermal heating zone from the cool environment. The heater may be constructed from a ribbon of a resistively heated metal, such as platinum foil.
