Abstract
A gas analysis device includes a light source configured to emit laser beam to a target gas, a reflection body which reflects the laser beam, a light reception device that receives the laser beam reflected by the reflection body, a container which contains the light source and the light reception device, and an alignment mechanism that includes an insertion member inserted from outside of the container to inside of the container to move, along a plane intersecting with the irradiation direction of the laser beam, at least any one of the light source and the light reception device.
Claims19
A gas analysis device comprising:
- a light source configured to emit a laser beam to a target gas;
- a reflection body reflecting the laser beam, wherein the reflection body includes a corner cube prism or a retro reflector;
- a light reception device receiving the laser beam reflected by the reflection body, wherein the light reception device includes a photodetector;
- a container containing the light source and the light reception device;
- and
- an alignment mechanism comprising an insertion member inserted from outside of the container to inside of the container to move, along a plane intersecting with an irradiation direction of the laser beam, at least any one of the light source and the light reception device, wherein
- the alignment mechanism comprises:
- a floating base disposed inside of the container to be movable in the plane and that supports the one of the light source and the light reception device;
- a plunger mechanism that urges the floating base along the plane;
- and
- a push screw member that pushes the floating base along the plane against urging of the plunger mechanism.
