When OGI technology was in its infancy, Providence Photonics started working on autonomous leak detection algorithms and systems to continuously monitor equipment and raise an alarm when a leak was detected. Throughout the years, Providence Photonics has been the leader in the OGI field and pioneered quantitative optical gas imaging (QOGI) technology. In 2016, Providence Photonics launched the first QOGI commercial product QL100, and upgraded it to QL320 in 2017.

In 2019, Providence Photonics formed a strategic partnership with the world leader in OGI camera manufacturing, FLIR Systems. Since then, Providence Photonics technologies have been integrated into FLIR’s OGI products. Currently, these products include:

​

• QL320: a tablet based QOGI system that can be connected to FLIR GF320, GFx320, GF620, GFx620, Gx320, and G620 cameras and quantify volumetric or mass leak rate when the leak is detected.

• In-Camera-Quantification: The QOGI technology has been embedded in FLIR’s new G-series camera launched in 2023, allowing the users to quantify the leak as the leak is detected without additional equipment.

• ADGiLE: a fixed, mounted autonomous OGI system that continuously monitors gas leaks from equipment and raises alarm when a gas leak is detected.

More information on QL320, G-series camera models, and ADGiLE system can be found on FLIR website. The links to these products can be found on the right panel of this page under Resources.
