Lens tubes are optical devices designed to penetrate the furnace wall and mounted on CCD cameras to view various mixing and combustion, processes in coal-, oil-, or gas-fire furnaces. TVL Series Lens Tubes can provide straight on, or side angle viewing. Some of them contain inner and outer shells, and cooling air is supplied between the shells and exhausted out the objectives lens end opening.

Additionally, TVL Series Lens Tubes are ideal for those tough situations where the lens tube and CCD camera must be hidden to surveillance hostile objectives.

Each of TVL Series Lens Tubes features pinhole input aperture, sapphire window, high optical resolution, large field of view angle, long and fine shape, and can operate in the high temperature environment lower than 150°C. With these careful design and manufacture, TVL Series Lens Tubes can inhibit the foreign particles on the front end lens surface, and have long-life in the hot and dirty environment
