Ordering Info

The White broadband gas absorption cell is mainly designed for spectral technology applications such as infrared Fourier transform. The detection light is 2-12um mid-far infrared incoherent light source (broadband).In response to the needs of high temperature and corrosion resistance, special metal materials with anti-corrosion treatment have been developed for both the main body and optical components. The working temperature of the chamber can withstand up to 200 ℃, and it can work stably and reliably for a long time under humid and corrosive gas conditions. Accurate measurement and analysis of major gas components, including SO₂, NOx, VOCs, NH₃, O₂, CO, CO₂, HF, HCl, H₂O, etc., are carried out, including monitoring of major atmospheric pollutants, The monitoring of coal-fired flue gas emissions, waste incineration emissions, pollutants in chemical industrial parks, and industrial online control have broad application prospects.

Note: 1. The diameter of the incident light beam is defined as the size of the incident light at the aperture of the air chamber. If the diameter of the incident light beam exceeds the requirements, energy loss will occur due to the built-in aperture of the air chamber.

2. If the half angle of the incident beam exceeds the requirements, it will cause energy loss, and the reflector may not be able to collect all the incident beam. The stray light will not be reflected in the cavity according to the designed optical path, affecting the optical performance of the air chamber.

3. Full-band light transmission efficiency refers to the average light transmission rate in the 2.5um-12um band ≥ 40%.
