Series Name : Image Intensifier Tube
Name : FOM 1800 Green Phoshor image intensifier tube
The MHNV Image Intensifier Tube (IIT) is a type of electro-optical device. Its working principle is to use a photocathode to convert faint light into electrons. These electrons are accelerated and multiplied under high voltage, then strike the phosphor screen, thereby forming visible images with higher brightness. Its core components include a photocathode, a microchannel plate (MCP), and a phosphor screen. With these components, the device can achieve night vision in extremely dark environments such as starlight, and is currently widely used in security and scientific research fields.
