Photon counting head

H13467-01

The H13467 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 H13467 series has a function of over light detection output for indicating the excessive light operating condition.
