A radiation transmitting apparatus (20) includes at least one radiation emitting element (11) enclosed in an envelope (12). The radiation emitting element (11) emits radiation including radiation in a first wavelength range and the envelope (12) absorbs and is heated by radiation in the first wavelength range. The apparatus (20) further includes means to absorb radiation in the first wavelength range which means may comprise a reflecting structure (10) which reflects radiation other than that in the first wavelength range. Dissipating means are included to dissipate the heat generated in the means to absorb radiation in the first wavelength range by absorption of radiation in the first wavelength range. The apparatus (20) is intended to be embodied as a radiant bulb furnace. |
