High Speed Hybrid Photodetector Module
Hamamatsu Photonics introduced a hybrid photodetector module, the H10777. The hybrid photodetector (HPD) dispenses with the traditional metal dynodes found within a conventional photomultiplier tube (PMT) and instead photoelectrons are accelerated in a high electric field onto a silicon avalanche diode target, which is connected to form the cathode/output of the device.
The The H10777-01 offers a TTS (transit time spread) of 35 ps FWHM. Intended applications include fluorescence lifetime measurements (using TCSPC = time correlated photon detection methods), time-of-flight measurements in high-energy physics experiments, LIDAR, biomedical research, atmospheric pollution measurement, laser scanning microscopy and fluorescence correlation spectroscopy.
