Wide dynamic range PMT module

H13126-03

This H13126-03 is a wide dynamic range photomultiplier tube module with 3 signal outputs containing a PMT with effective area of 22-mm diameter and circuits of a high-voltage power supply, a high-speed photon counting and amplifiers. One output of this unit is digital for counting single photons and the other two outputs are analog for converting the output signal voltage to the number of photons. By bringing together these three results measured at the same time, a dynamic range of 10 orders of magnitude can be achieved at pulsed input light conditions.

Features

●Maximum counting rate: more than 5 x 10¹¹ s⁻¹

●DC to 20 MHz bandwidth
