10 m Optical Path Ultra-Compact Gas Absorption Cell, 700-800nm

The 10-meter optical path gas absorption cell is used for the spectral analysis and detection of various gases. The optical path structure of the gas chamber features an independently patented design with excellent optical stability, utilizing a flat-wave gas chamber (SlimBoss Gas Cell). It is equipped with a highly stable optical packaging structure, primarily composed of the gas chamber body, mirrors, standard fiber optic connectors, gas inlet and outlet, and a vibration-damping base. The unique suspended optical path design ensures outstanding vibration and temperature stability, enabling it to work reliably in various complex environments. This makes it highly suitable for real-time online detection of various gases. The system has low noise and is ideal for trace gas analysis.

Product features：The gas chamber structure is stable, resistant to vibration, and external compression. 、 The gas chamber is compact, lightweight, and easy to transport. 、 Long effective optical path. 、 Input uses standard single-mode fiber, and output can be in PD or fiber optic form. 、 Industrial online control.

Application area：Display panel testing 、 LED lighting flicker analysis 、 Toy light flicker frequency and power measurement 、 Gas analysis
