The EMI Super Emitron TV camera
inside view
This is the camera with the cover removed. The tube can be seen with the
neck offset towards the side. The amount of rotation was adjustable to
compensate for the rotation of the picture in the Image section of the
tube, this varied as the electron image was brought into focus on the
target mosaic.
The Super Emitron had an Image Section in front of the target and this
meant that the image from the lens was formed on this smaller photo
target which was much nearer the lens thus removing many of the constraints
suffered by the standard Emitron lenses. Additionally it was some 10
times more sensitive enabling the use of telephoto lenses in poor light
conditions.
