Compact Head-on PMT Photosensor Modules H7827 Series The H7827 series photosensor modules incorporate a 19-mm (3/4") diameter head-on photomultiplier tube, a high-voltage power supply circuit and a low noise amplifier. Two types of amplifiers are available with a current-to-voltage conversion factor of 1 V/µA or 0.1 V/µA and a frequency bandwidth of DC to 20 kHz or DC to 200 kHz. Two types of photomultiplier tubes with different spectral response characteristics are provided for measurement in the visible range or visible to near IR range.
