Document Type and Number:
WIPO Patent Application WO/2022/259680
Kind Code:
A1
Abstract:
Provided is a gas analysis device which prevents a laser light source and a photo detector from being exposed to a high temperature by being spaced apart from a gas cell and is more practical than the prior art, the gas analysis device comprising: a gas cell 10; a laser light source 20 or a photo detector 30 which is disposed to be spaced apart from the gas cell 10; and a laser light transmission mechanism 50 disposed between the gas cell 10 and the laser light source 20 or the photo detector 30, wherein the laser light transmission mechanism 50 has one or a plurality of tubular members 51, and the optical path L of the laser light is configured to be formed in an inner space of the tubular members 51.
