The invention discloses a device for realizing pipeline light path collimation adjustment for a laser online gas analyzer, which can be used for protecting an optical lens placed in a pipeline. The device comprises a flange adjusting assembly, a lens placing pipeline, a connecting pipeline, a lens adapter, a locking ring and the like, wherein each mechanism is connected into an entire set of device, so that the collimation adjustment of the pipeline can be realized, and the pitch angle of the optical lens can be adjusted; a unique connecting way of engaging the external thread of the pipeline with the internal thread of a lantern ring is adopted, so that the optical lens is prevented from being damaged by metal scraps; and an effective optical cavity length can be selected according to a practical requirement, and convenience is brought to installation and detachment.
Description
technical field [0001] The invention relates to the field of optics, in particular to a device for adjusting the collimation of the pipeline optical path for a laser online gas analysis instrument. Background technique [0002] At present, known optical cavities that require a long optical path are usually directly welded or bolted by welding flanges. Due to errors in the production process of the processed parts or standard parts, it is easy to cause the alignment of the optical path after welding or connection. At the same time, the optical lens (window, high reflection mirror, etc.) is directly placed, and after the overall structure is tightened, the metal debris generated during the meshing process of the internal and external threads of the optical pipe will remain in the optical cavity and cause damage to the optical lens. At the same time, the external rubber flat gasket for sealing is prone to damage during the multiple meshing process of the internal and external t...
