Gas analyzer with led light source and compensation system
A gas analyzer patent (Publication Number: US12000774B2) has been granted for a device that includes an LED light source producing collimated beams with varying energy levels, a reference sensor to detect these levels, and a processing system to compensate for energy variations due to temperature changes. The gas cell within the analyzer features mirrors to reflect the beams, a detector to generate signals, and lenses for focusing and maximizing light collection efficiency.
The patent claims detail various aspects of the gas analyzer, including the configuration of mirrors to re-focus the beams, dielectric coatings for reflectivity, specific bandwidth and peak values for the beams, pass line distance, and the number of reflections within the gas cell. Additionally, the patent covers the use of a thermo electric cooler to regulate LED temperature, selectable set temperatures, ambient temperature detection, and specific angles for beam divergence. The device aims to provide accurate gas analysis by compensating for energy fluctuations and optimizing light collection efficiency within the gas cell.
