High Speed Hybrid Photodetector Module

The advantage of the HPD construction is single photoelectron resolution capability, combined with very fast response compared to conventional PMTs. Two versions of the H10777 are available, a bialkali tube with spectral response range from 220 nm to 650 nm, and a GaAsP semi-conductor cathode version working from 300 nm to 720 nm, with a peak QE of > 45 %.

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.
