Abstract: The application relates to an infrared radiation source for a gas analyzer and a method for generating infrared radiation. The infrared radiation source comprises a body (6), thermal insulation material (5) adapted inside the body (6), a radiant element (1) fitted inside the insulation material (5), elements (2, 3) for feeding electric energy to said radiant element (1), and a channel (7) formed in said body (6) and said thermal insulation material (5) in order to pass the radiation generated by said radiant element (1) to the gas under measurement. According to the description, at least the thermal insulation material (5) adapted in close proximity to the radiant element (1) has a low thermal conductivity and the emissivity of the radiant surface (11) adapted in close proximity to the radiant element (1) is greater than 0.5 at the operating temperature of the source.
