A high temperature heater lamp including a ceramic envelope is disclosed. The ceramic envelope is substantially infrared transparent and is composed of a refractory ceramic. The heater lamp also includes two lead wires communicatively coupled via a filament. The filament is enclosed within the ceramic envelope, which is evacuated. The heater lamp may include at least two metallic IR shields within the ceramic envelope, at least one located on either side of the filament. The filament may be tungsten, a carbon filament, or molybdenum. At least one end of the ceramic envelope may be sealed with a metal cap affixed to the ceramic envelope by a high vacuum sealant. The heater lamp may be configured to operate at above 1500° C. The ceramic envelope may have a wall thickness less than 1 mm thick.

The invention relates to an infrared device comprising a resistive element suspended in a cavity formed in a main element, and capable of transmitting infrared radiation when it is fed with an electric current. In particular, the main element is at least partly covered on the outer surface thereof and/or the inner surface thereof with a reflective coating. The use of the reflective coating makes it possible to at least partly contain infrared radiation transmitted by the resistive element in the cavity.
