Product Description

The photograph above shows the typical bottle shape of the early instrument type CRT and its metal shielding casing. Anyone who has seen inside a modern television or computer monitor (danger - very high voltages present when in use) will have seen the much fatter, squatter versions which are still used.

On the right of the tube is the electron gun, where a heated filament produces a cloud of electrons. These are focused into a beam and accelerated towards the fluorescent display screen on the left by an anode with a high positive voltage. The beam is deflected to write the electron beam on the fluorescent display and so produce the visible numbers.
