The history of ET Enterprises Limited can be traced back to the 1930s when, as part of EMI, it ﬁrst became involved with light detection technologies. Specialisation in the development and manufacture of photomultiplier tubes started in the late 1940s, and the company continued to grow to become a major international supplier of low-level light detection devices and systems. We offer a wide choice of high quality photomultiplier tubes, photodetector modules and associated electronics, together with comprehensive technical and application support, and competitive prices. Along with our photomultiplier manufacturing facility, we also have our technical glass manufacturing company, Plowden and Thompson, operating out of the UK. Now a subsidiary of Ludlum Measurements Inc., Texas, ET Enterprises Limited has the beneﬁt of the combined resources of the production facilities of ADIT, a US based producer of photomultiplier tubes, and ET Enterprises’ development facilities. Outside the US, ET Enterprises distributes and supports ADIT brand photomultipliers.
