Tektronix has a long, rich history in custom cathode-ray tube (CRT) design and manufacturing, starting in 1954 and ending in 1996.  This page is an index to the various articles and information on this website.

As the articles below describe, the need for superior CRT performance over that obtainable in the open market was the initial driving force for this move to vertical integration and was amplified through the years as competitors took the same path, until high speed semi-conductor signal capture devices allowed an oscilloscope’s waveform to be displayed on commodity-level flat panels.

The drive for CRT performance and quality improvements led to many innovations including Manufacturing processes, electron gun design and component fabrication, ceramic funnels, phosphor manufacturing, etc.
