Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'иконоскоп' which is the direct transliteration and correct equivalent. There is no direct false friend, but the word is highly specialized.
Common Mistakes
- Spelling: 'iconiscope', 'iconascope'. Pronunciation: stressing the first syllable (EYE-con-oh-scope) instead of the second (eye-CON-oh-scope). Using it to refer to modern camera components.

FAQ
Frequently Asked Questions
No, the iconoscope is entirely obsolete. It was superseded by more advanced camera tubes like the orthicon and vidicon, which were in turn replaced by solid-state CCD and CMOS sensors.
The iconoscope was invented by Vladimir Zworykin, a Russian-American engineer, who filed a patent for it in 1923 while working for Westinghouse.
It is derived from the Greek words 'eikōn' (image) and 'skopein' (to look at, to examine). So, it means 'image observer'.
It was one of the first practical all-electronic television camera tubes, making purely electronic television systems possible and paving the way for modern broadcast television.
