Photon Counting Head H10682 Series
The H10682 series is a photon counting head device consisting of a metal
package photomultiplier tube, along with a high speed photon counting circuit
and a high-voltage power supply 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 H10682-110 has the super bialkali (SBA) photocathode and the
H10682-210 has the ultra bialkali (UBA) photocathode, so they have higher
sensitivity than conventional photon counting heads.
The H10682 series has also over light detection function to output a signal at
the state that an output count falls by excessive incident light. By this signal,
measurement data can be judged that it is normal or not.
