Description

Technical Field

[0001] The utility model relates to the technical field of instruments and meters, in particular to an adjusting tooling mechanism for a measuring cell of a spectrum analyzer. Background Art

[0002] The gas measuring cell is one of the core components of analytical instruments that perform gas detection based on spectroscopy. The basic principle of a spectrum analyzer is to detect and analyze gas components through the interaction of laser light of a specific wavelength with gas molecules. The laser enters the measuring cell at a specific angle and position. By adjusting the two mirrors within the measuring cell, the laser light is reflected multiple times in a specific optical path pattern, ultimately exiting the measuring cell at a specific angle and position. Therefore, the key to adjusting the measuring cell lies in adjusting the position and posture of the mirrors at both ends so that the laser's incident and exit angles, as well as its reflection within the measuring cell, conform to the desired optical path pattern. Without a stable and accurate measuring cell adjustment fixture system, adjusting the optical path of the measuring cell is often extremely difficult, time-consuming, and labor-intensive. This is especially true for measuring cells with long optical paths. Whether used in the laboratory or in production, professional technicians must expend considerable time and effort to modulate the optical path to the corresponding pattern, significantly impacting process efficiency and increasing the company's time costs.
