Image Intensifiers

All specification only show the minimal specifications manufacturers will at least meet. Often enough the real specifications of each tube are above those by far. Photonis Commercial Res: 30 lp/mm SNR: 12 Sens: 270 uA/lm Photonis cheapest IIT they still sell. Here is everything that does not meet at least XD-4 specifications. Tubes will have […]

Electron Acceleration

The basis of night vision is a conversion of energy that occurs within a vacuum tube. An image intensifier tube collects photons through an objective lens, via a photo cathode converts them to electrons, increases the electrical energy by electron acceleration or multiplication, converting the electrical energy back to photons using a phosphor screen and […]
