Description

The PMS-800 module is a gated photon counter and a multiscaler at medium time resolution. The board is applicable to luminescence decay of inorganic samples, phosphorescence, delayed fluorescence, chemo luminescence and LIDAR. The board offers a PCIe interface and can be easily installed in nearly all PCs.

General Information

The PMS-800 is a module with four fast gated photon counting and multiscaler channels. All devices contain ultra-fast discriminators for the counting and gating inputs.
The PMS counts all pulses with an amplitude greater than a selectable discriminator threshold and the inputs can be gated to count pulses either inside or outside an externally applied gating pulse. The on-board timing and control logic controls the counting interval and the storing of the counting results. Different operating modes allow for steady state measurements (luminescence spectra), waveform recording (luminescence decay curves) and event recording (e.g. for single molecule detection). The PMS boards can be used for count rates up to 800 MHz and can be gated by pulses down to 1 ns FWHM. Therefore, the modules are applicable not only for photon counting, but also for other fast pulse counting applications.
