ABSTRACT:
In an infrared radiation source, especially for a multi-channel gas analyzer, a radiant body (3) is provided with a reflector (4) disposed behind it, and a window (5) of calcium-fluorite at least partially covering the radiant body (3) is provided, the radiant body (3) being partially surrounded at its rear by a cup-like case (6) whose circumferential margin is hermetically joined to the window (5) by an intermediate ring (19). The interior (7) of the radiant source can be pumped empty of air through a passage (8) in a tube connection (9) formed by the case (6) or provided with an oxidizing atmosphere, thereby achieving a high insensitivity to the position of the infrared radiation source.
