Ultra-small Gas Absorption Cell with 10m Optical Path

The 10m gas absorption cell is applied to spectral analysis and detection of various gases. The light path structure of the gas chamber uses a SlimBoss Gas Cell with excellent optical stability and high-stability optical package structure, which is mainly composed of a gas chamber cavity, a reflector, a standard optical fiber joint, a gas inlet and outlet, and a 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.
