The 10-meter optical input and electrical output gas absorption cell is used for various gas spectral analysis and detection. The optical path structure of the gas cell uses the self-patented design, the flat wave gas cell (SlimBoss Gas Cell) with excellent optical stability, and the auxiliary and high-stability optical packaging structure, which is mainly composed of the gas cavity, reflector, standard optical fiber connector, gas inlet and outlet, and shockproof base. The unique suspension optical path design has excellent vibration and temperature stability, can work stably in various complex environments, and is very suitable for online real-time detection of various gases. It has low system noise and can be applied to trace gas analysis..
产品特点The air chamber structure is stable and resistant to vibration and external extrusion、 The air chamber is small in size, compact in structure, and easy to carry、 The effective optical path is long、 The input uses standard single-mode optical fiber, and the output uses PD or optical fiber

10 meter optical path miniaturization chamber usage test
Using 2004nm and 2327nm DFB lasers, we built a TDLAS gas absorption system and measured the signal through the gas chamber.
For 2004nm DFB laser, it is used to measure the gas absorption concentration of CO2:
2004nm DFB laser measurement of CO2 gas absorption concentration amplitude
Compare with our database data:
For 2327nm DFB laser, used to measure the gas absorption concentration of CO:
2327nm DFB laser measurement of CO gas absorption concentration amplitude
Compare with our database data:
Verify that this absorption peak is the absorption peak of CO gas we measured at 2327nm
By comparison, we can find that after using the 10-meter miniaturized gas chamber, the measured gas absorption molecular amplitude becomes larger as the optical path lengthens, and a lot of detection noise is filtered out, the interference to the signal becomes smaller and smaller, and the measurement accuracy is improved.
