Plumbicon Television Camera Tube
The Plumbicon is a specialized cathode-ray tube used in professional broadcast television cameras for superior image quality and low-light performance. It functions as a photocathode tube converting light into electrical signals via electron scanning. This falls under HTS 8540.20.20 as a television camera tube, distinct from standard display CRTs.
Vidicon Camera Tube
Vidicon tubes are photoconductive cathode-ray tubes historically used in closed-circuit TV and early video cameras for reliable imaging in security systems. They feature a photocathode layer scanned by an electron beam to generate video signals. Classified under HTS 8540.20.20 as television camera tubes per the thermionic/photocathode heading.
Image Orthicon Camera Tube
