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 μPMT 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 μPMT assembly features a bialkali photocathode that is sensitive in the visible wavelength range and a divider circuit.
