Head-on PMT Photon Counting Head H11870 Series The H11870 series is a wide sensitive area photon counting head device containing a 25 mm (1") diameter head-on photomultiplier tube, a high-voltage power supply circuit and a photon counting circuit. The high voltage supply for photomultiplier tube and the discrimination level are preset to optimum values, allowing photon counting measurement by just connecting a +5 V supply. The H11870 series has a function of over light detection output for indicating the excessive light operating condition. A mount flange (E6264) is provided as an option for easy installation to measurement equipment. Specifications Parameter H11870-01 Input Voltage Max. Input Voltage Max.
