Oxygen 20 meter long optical path gas compact absorption cell (700-800nm)

Application of oxygen gas long path gas absorption cell for spectral analysis and detection of oxygen gas. The main body adopts Herriot Gas Cell with excellent optical stability, and the auxiliary and highly stable optical packaging structure mainly consists of gas chamber cavity, concave reflector, standard fiber optic connector, photodetector, gas inlet and outlet, and shockproof base. The unique suspension road design has excellent vibration and temperature stability, and can work in various complex environments, making it very suitable for real-time detection of gas lines. It has ultra-low system noise and can be applied to trace gas analysis.
