<p>PROBLEM TO BE SOLVED: To provide an infrared gas analyzer which can be miniaturized and simplified in structure. SOLUTION: Concave reflecting mirrors 2, 16 are set to face each other. A light source 4 is arranged so that infrared lights S1 , S2 are projected from one concave reflecting mirror 16 to another concave reflecting mirror 2. A photodetector 5 is arranged at a position of in the vicinity of the position where reflecting luminous fluxes A3 , B3 of infrared lights S1 , S2 multiple-reflected between the concave reflecting mirrors 2 and 6 after projected from the light source 4 are converged. A gas including a gas to be measured in sent into the space between the concave reflecting mirrors 2 and 16, and the degree of characteristic absorption in measured.</p> |
