Image Intensifier Tube (IIT) is the heart of Night Vision. Night Vision device performance is defined by the IIT quality. Up to 80% of the overall cost of a night vision device is the cost of IIT. Only five companies in the world have the technical know how and are engaged in mass production of IITs. Newcon Optik is proud to be a member of this club. Along with the proven generation 2+ we also produce the more advanced Generation 3 tubes. Both 18 and 25 mm models are available. Our Tubes are fully compatible and interchangeable with ANVIS models available from competing manufacturers.   Tube Model Description Specs Devices* NC064322 NCXT4322 N3064322 COMPACT NON INVERTING TUBE COMPATIBLE WITH NVS 7 AND OTHERS NC064329IC NCXT4329IC N3064329IC “FAT” ANVIS INVERTING TUBE COMPATIBLE WITH AN/PVS 5 AND OTHERS NC064331SC NCXT4331SC N3064331SC AN/PVS 7 COMPATIBLE TUBE NC063631IC NCXT3631IC N3063631IC ‘Slim” ANVIS INVERTING TUBE COMPATIBLE WITH AN/PVS 6,9,14 AND OTHERS NC104331_25 COMPACT NON INVERTING 25 MM TUBE COMPATIBLE WITH NVS 7-2/WA NC107663IF 25 MM LARGE INVERTING TUBE, MX9644 TYPE.
