Product Variations

The H7467 is a photon counting head designed for photon counting by simply

connecting to a PC (personal computer). The H7467 houses a metal package

photomultiplier tube, high-voltage power supply circuit, photon counting cir-

cuit, 20-bit counter and microprocessor in a compact package. Data transfer,

measurement time and other necessary adjustments are controlled by com-

mands from the PC through the RS-232C interface. The photon counting cir-

cuit discrimination level and the high voltage supply for photomultiplier tube

are preadjusted to optimum levels prior to shipment so that the H7467 can be

easily operated by simply supplying +5 V.
