The ultra-compact photomultiplier tube is fabricated through the use of in-house semiconductor processes for MEMS (micro-electro-mechanical systems) devices. It can be mass produced, is only 1/7th of the volume and 1/9th of the weight of the smallest conventional photomultiplier tube. The characteristics of this new PMT will enable the development of high-precision measurement instruments for individual users, such as for point-of-care medical testing and environmental monitoring. The new assembly features a bialkali photocathode that is sensitive in the visible wavelength range and a divider circuit.
Next-generation micro photomultiplier “µPMT” for point-of-care testing and other applications. The shipping of samples to manufacturers of analytical and measurement instruments began in november.
