Marconi Experimental Two Tube colour Television Camera

This is the optical layout of the camera. At the bottom a half silvered mirror defects light to the right and it is reflected upwards, though a relay lens and another two mirrors and thus to the photocathode of the top tube. Both tubes were 3 inch Image Orthicons.

This may be the first example of a camera with a colour striped tube. This was a 2 tube camera with a luminance tube and a striped tube for the colour.

The colour tube (top) was of lower resolution than the luminance tube (bottom) easing the difficulties of registration
