3-meter long optical path gas absorption cell 750-3000nm

According to the Tunable Semiconductor Laser Absorption Spectroscopy (TDLAS) technique, a Herriott cell concave reflector is used to construct a multi cavity long path gas cell. The reflector lens is coated with high-quality gold, silver, and protective layer coatings, which have high reflectivity. The compact design provides a relatively long absorption path, and the high-precision optical cavity gas pool is made of high-quality corrosion-resistant materials, suitable for industrial product application development, high-sensitivity gas analysis, major universities, scientific research, online environmental monitoring, etc. Can be directly installed with standard light source collimator, interface M11X0.5 thread. No need to add mirrors or adapters to adjust the light, it is particularly convenient to use.
