30m long optical path gas absorption cell (Aperture type)

According to the tunable semiconductor laser absorption spectroscopy technology (TDLAS), a Herriott cell concave reflector is used to build a multi-reverse cavity long optical path gas cell. The reflective lens is plated with high-quality gold, silver and protective layer coating, which has high reflectivity. The compact design provides a relatively long absorption light path. The high-precision optical cavity gas cell is made of high-quality corrosion-resistant materials as a whole. It is suitable for industrial product application development, high-sensitivity gas analysis, major universities, scientific research, online environmental monitoring, etc. The standard light source collimator can be directly installed, and the interface is M11X0.5 thread. There is no need to add an external reflector or adapter adjustment to align the light, which is very convenient to use.

Product features：It adopts concave emission focusing optical path design, mirror anti-reflection film, protective film, and shockproof mounting base. It has stable optical path, direct access to collimated light source, and is easy to use. It is equipped with gas pool temperature and pressure display function, which is convenient for controlling gas pool temperature and pressure and safe operation. It is made of stainless steel, high-quality aluminum alloy oxidation treatment, and quartz glass. It is equipped with O-rings, which has good sealing and real-time observation; it is equipped with standard gas joints, which is convenient for use in various occasions.

Application area：Monitoring tasks in industrial environments 、 Infrared absorption spectroscopy in scientific research 、 Industrial online monitoring

Note: The gas cell needs to be placed on a stable workbench, the power fiber at the front end is connected to the FC/APC interface, the incident power is turned on, the light beam is emitted multiple times between the reflectors in the cell, and is emitted from the light exit hole at the rear end.

Warning:

1. Do not disassemble the gas seal and the fixed parts for the light in and out.

2. Do not look directly into the light exit hole!
