Beschreibung
Zusammenfassung:	The utility model provides a long-optical-path optical cavity. The long-optical-path optical cavity comprises a light source, a gas chamber, a detector, a first reflector, a second reflector, a first diaphragm hole and a second diaphragm hole, the first reflecting mirror and the second reflecting mirror are respectively arranged at two ends of the air chamber, the first reflecting mirror and the second reflecting mirror are both concave mirrors, and the first reflecting mirror, the second reflecting mirror and the air chamber form a closed space; the first diaphragm hole is formed in the center of the first reflecting mirror, and the second diaphragm hole is formed in the center of the second reflecting mirror; the detector is arranged at the rear end of the first diaphragm hole, the light source is arranged at the rear end of the second diaphragm hole, and the light source is a light source with a divergence angle. The long-optical-path optical cavity has the advantages that the optical path is longer, and t
