UV(ultraviolet) image intensifier is a vacuum image device with Cs2Te (Cesium Tellurium) photocathode. It converts the incident ultraviolet(UV) light from the optical lens into electronic signal, then the electronic signal is converted into responding visible image on the phosphor screen. Defects of different sizes can be seen on the screen when it works. A system is build to inspect the distribution of the defects, then the sources and category of the defects of the view field are analyzed, including photocathode, microchannel plate and phosphor screen, some improving technique is brought to decrease the defects.
