The famous 4.5 inch Image Orthicon monochrome camera tube was devised originally (1947) in the USA by RCA. The prototype was perfected by EEV and Marconi in the UK and the first production models went into service in the mid-1950s. Later versions used the 'ELCON' target glass, making the EEV 4.5 inch I.O. the tube of choice for tv stations throughout the world. EEV I.O. tube manufacture closed in 1982 after sales of over 250,000 units.
