Photocathode Tube for Night Vision from Canada
This S-25 spectral response photocathode tube converts available light into electrons via photoelectric effect, amplifying them for low-light imaging in night vision devices. It features a gallium arsenide photocathode optimized for near-infrared sensitivity. Falls under HTS 8540.89.00.60 as a light-sensing photocathode tube, distinct from complete night vision cameras.

Import Tips
• Distinguish between standalone tubes (8540.89) and assembled night vision cameras (8525.83) with clear component documentation
• ITAR/EAR export controls may apply; obtain proper licenses for military-spec photocathode materials
• Label spectral response curves to prove light-sensing function separate from thermal imaging classification
