A minimal invasive visualization system for industrial combustion chambers at 310 nm

The monitoring of industrial combustion processes at high temperatures beyond 1000°C (e.g. in glass production) is a challenge for the used optical detection system. We present a minimal invasive endoscopic system designed for operation inside the combustion chamber. A three level cooling system protects the image intensifier based camera system inside the probe that can be inserted into the combustion chamber through existing inspection ports. The camera system is designed to detect light in the UV spectral band of OH- Emissions, which allows to visualize the flames on the background of the hot chamber walls.
