How the high temperature endoscope captures images inside an operating furnace while staying protected.
Place 1.mp4 in the site root to play the video here.
The imaging system uses a camera and a high-temperature pinhole lens to collect the furnace image and display it directly on the camera.
The camera and lens sit inside the protective cover, which extends through an opening in the furnace wall to view the interior.
The protective cover has three layers: the outer layers carry circulating cooling water that removes heat from the cover.
Compressed air on the innermost layer directly cools the lens and blows out of the front observation hole, protecting the lens.
The cooled probe extends through the furnace-wall opening.
The pinhole lens collects the interior image.
The camera shows the furnace interior in real time.
Images and video are captured for evaluation.
