The H11123 is a photon counting head device consisting of a 28 mm (1-1/8") diameter head-on photomultiplier tube, a high-speed photon counting circuit, and a high-voltage power supply circuit. The high voltage power 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 H11123 can operate at high count rate. The effective photosensitive area is as large as 25 mm in diameter, so the incident light can be collected very efficiently.
