Hamamatsu release 12 types of high QE photomultiplier tubes since October as the first group. Other types will come to the market continuously upon being ready.


UBA (Ultra Bialkali), SBA (Super Bialkali) Photomultiplier Tube Series
Always been a leader in Photonic Device performance, Hamamatsu has now developed a PMT with a quantum efficiency (QE) of 43%. In all kinds of high-precision light measurements, high sensitivity and high QE are absolutely essential elements in extending detection limits and unlocking new knowledge. For Hamamatsu, however, this 43% QE is just one more step along the road. Aiming for the peak of PMT performance will open up all kinds of new possibilities.
