Photon counting made easy with new electronic modules from ET Enterprises


The MCS-CT3 is a new multi-channel scaler/counter-timer from ET Enterprises Ltd which can be interfaced with a PC or Laptop via a USB port to operate as a cost- effective, high performance pulse counting instrument. When used with a compatible photo-detector module, such as the new ET Enterprises PDM02-9111-TTL series, it becomes a wide dynamic range photon counting system.


It is a compact electronics mudule which records pulse counts as a function of time and stores them in channels, each of which has a user-selectable time window, or ‘dwell-time’. Operation and data retrieval are controlled by a PC using Windows XP, or later, operating systems and the open-source software supplied with the MCS-CT3. A LabVIEW virtual instrument program option is also supplied.


Power for the MCS-CT3 is supplied via the PC USB cable and a low voltage output socket is provided to power the photo-detoctor module.


Using the MCS-CT3 with a photo-detector module type PDM02-9111-TTL (supplied separately) enables the following performance to be achieved:


• •


• •


count rates up to 150MHz


trigger input for synchronous counting channel widths from 200µs to 9999hr number of channels from 1 to 65535, or continuous


• •


• •


supplied with open-source software which can be customised compact and cost effective


two counters can operate simultaneously can be supplied as a complete photon counting system


Contact us to learn more about how we can help to make your photon detection needs easier. And, of course, we have a wide range of photomultipliers for your application, whether photon counting or analogue,


together with associated hardward such as HV supplies and light-tight housings.
