FAQ
Frequently Asked Questions
No, it is completely obsolete. It was superseded by the Plumbicon and later by solid-state CCD and CMOS sensors.
Its key advantage was very high light sensitivity, which made it suitable for live television broadcasts in lower-light studio conditions.
"Orthicon" is derived from the Greek 'orthos' (correct, straight) and 'eikōn' (image), referring to its method of producing a correct or accurate electron image.
Almost certainly not. It is a highly specialised historical term relevant only to specific technical or historical contexts.
