Electric and Musical Industries Ltd. (EMI) Emitron long necked television camera tube
Tube de prise de vue
James McGee and William Tedham applied for a patent for a new device they dubbed "the emitron".
Cameras developed for the BBC by the Marconi-EMI Television Co. Ltd. were produced in January 1934. When the
world's first regular high-definition television service began broadcasting from Alexandra Palace in London
in 1936, the cameras in the studios used the Emitron tube.
Their low sensitivity (2500 Lux at f3) was nevertheless high enough for outside television
broadcasts (including the 1937 Coronation), as well as for studio productions. Since the emitron cameras produced
practically no lag in the picture, moving objects were reproduced clearly.
