Abstract
A sealed infrared radiation source includes an emitter membrane stimulated by an electrical current conducted through the membrane, which acts like an electrical conductor, wherein the membrane is mounted between first and second housing parts, at least one being transparent in the IR range, each housing part defining a cavity between the membrane and the respective housing part of each side of the membrane. The housing parts are at least partially electrical conductive, and a first of the housing parts is electrically coupled to a first end of the electrical conductor and insulated from the second end of the electrical conductor, the second housing part being electrically coupled to a second end of the electrical conductor and being insulated from the first end of the electrical conductor, thus allowing a current applied from the first housing part to the second housing part to pass through and heat the membrane.
