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.
