Morphology

orthicon = icon (semi-transparent) = ortho + icon

The element 'icon' (image) gives a clue to the meaning, but 'ortho' is a technical combining form unfamiliar to many learners and the resulting term names a specific technical device rather than a general 'correct image'.

Etymology

The word orthicon comes from Greek parts orth- meaning 'correct' or 'straight' and -icon meaning 'image'. So an orthicon was a television camera tube that tried to make a 'correct' picture into an electronic signal.
