Description
General Information
The PMS-800 module is the direct successor of the PMS-400A. As a gated photon counter and multiscaler it can be used in luminescence decay of inorganic samples, phosphorescence, delayed fluorescence, chemo luminescence and LIDAR applications. It contains all features of the PMS-400A with a significantly improved time bin width of down to 4 ns, reduced dead-time of 1.25 ns and two additional input channels in a single module. Furthermore, in event threshold mode, events can be streamed indefinitely and are not limited to the internal memory of the module.
Incoming pulses are counted in time bins and, if desired, can be filtered with a gate input associated to each channel. The timing data can be processed in 3 different modes inside the module: multiscaler, triggered accumulation and event threshold mode.
In multiscaler mode, the module records pulses in a single time sweep across up to 64k bins. The measurement can be started by software or upon the occurrence of an external trigger signal.
In triggered accumulation mode, sweeps are repeated at high rate, each started by an incoming trigger signal. This mode allows for fast Time Correlated Single Photon Counting (TCSPC) with photon rates of up to 800 MHz per channel and trigger rates of up to 50 MHz.
In the event threshold mode, incoming pulses can be streamed for a virtually infinite amount of time. To filter background noise, a threshold can be applied to the count in each time bin and only bins with higher counts will be registered.
Measurement Software Included
The module can be integrated into a customized measurement software by means of a supplied DLL and associated Python libraries, which allow for quick prototyping.
We also supply a free measurement GUI with the module, the BH-PMS800 software, to execute the basic functionality, display various types of measurement results and process data into various commonly used file formats.
