Harnessing Laser Light to Revolutionize Gas Sensing Technology

Gas molecules absorp specific wavelengths of laser light. The absorption of laser light from an excitation laser heats up the gas molecules. This is a selective, accurate and non-contact effect, making this suited for reliable and robust gas sensing as oppossed to electrochemical sensors.

With direct absorption spectroscopy, the remaining laser light is detected on a photodetector (PD) and processed to calculate the gas concentration. For this technique, strong lasers and long optical paths are required for accurate measurements.

How Our Dual-Laser Sensor Tech Delivers Unmatched Accuracy in Gas Detection

With our sensor technology soluition we add a second laser, creating two optical paths:

1.The top path is the reference path which measures environmental effects

2.The bottom path is the measurement path which is overlapped with an exciation laser.

The difference between both paths gives us a stable reading in the absent of gas molecules.

How Dual-Laser Tech Revolutionizes Gas Detection with Precision and Efficiency

As gas molecules enter the optica paths, the bottom path heats up creating a temperature difference between the two paths. From this difference the exact gas concentration is calculated.

Having two lasers reduces the influcence of environmental effects. Using a second laser also reduces the requirements for the exication laser and path length. This enables us to create a robust gas sensor with low power lasers and a small optical path.
