In this manuscript, … Webb1 nov. 2024 · Micro-channel plate photomultiplier tube (MCP-PMT) is a kind of photosensitive device with single photon detection capability and great time resolution, which is also called Fast-PMT (FPMT). The characteristic of MCP makes the MCP-PMT capable of reaching great spatial resolution with multi-anodes.
WebbThe maximum count rate of fast MCP-PMTs, however, is 10-100 times lower than that of fast PMTs. Therefore, the acquisition speed with MCP-PMT based systems is limited. With a fast PMT operated close to its maximum count rate we were able to record a fluorescence lifetime image of a beating myocyte in less than one second.
WebbThe separation of the decay components and the accuracy of the amplitudes and lifetimes improves substantially by using the ultra-fast HPM-100-06 and HPM-100-07 hybrid detectors.
