美国无线电公司电子光学和器件部为小型电视彩色广播摄象机设计了 BC4398硒砷碲摄象管。该管使用在鹰眼(Hawk—eye)手提式录象机上。400电视行时的典型振幅响应为40%,典型惰性特性小于2%,兰光
The U.S.A. radio optics and electronics division designed the BC4398 selenium arsenic and tellurium phototube for small television color broadcast video cameras. The tube is used on Hawk-eye portable video recorders. The typical amplitude response at 400 TV lines is 40% with a typical inert characteristic of less than 2%, blue light
