HPD (HYBRID PHOTO-DETECTOR) MODULES H8236-07, -40 PRELIMINARY DATA OCT. 2000 PATENT PENDING The HPD (Hybrid Photo-Detector) is a new vacuum photo-detector including a photocathode and an avalanche diode. The HPD provides a gain of more than 1000 in a single multiplication process called 'electron bombardment multiplication'. The photoelectrons from the photocathode are accelerated by a strong electric field to hit the avalanche diode and release a large number of electron-hole pairs corresponding to the acceleration energy. This excellent first multiplication process enables the HPD to achieve excellent multi-photon energy resolution. This first multiplication process is followed by the second avalanche mode multiplication to provide sufficient gain for a variety of applications. H8236 is an HPD module, containing high voltage power supplies and a pre-amplifier. FEATURES APPLICATIONS ● Able to discriminate multi-photon events ● Low excess noise ● High Q.E. from 450 nm to 650 nm (H8236-40) ● Simple operation Built-in high voltage power supply and pre-amplifier ● Low after pulse ● Photon counting application ● Low intensity pulse detection ● Laser scanning microscope ● Particle counter SPECIFICATIONS Parameter Spectral Response Peak Sensitivity Wavelength Photocathode Material Quantum Efficiency E Effective Area Sensitivity A Bandwidth Signal Output Input Power/Current Recommended Control Voltage Range Signal Connector Control Connector Weight Offset (Typ.)
