Overview of SWISS Digital TCSPC
Digital TCSPC is designed for fast FLIM data acquisition and with the unique capability to cover the range from picoseconds to seconds with a time bin of 1 picosecond. Featuring 8 independent input channels, the unit records time-tagged time-resolved (TTTR) events in streaming mode.
Two versions of the module are available: the SWISS-2 unit allows for maximum data transfer rate of 8.5 M tags/second while the SWISS-3 reaches 65 M tags/second; dead time is 6 ns and 2 ns respectively. Decay times from the picosecond to the second time scales can be resolved (FLIM and PLIM). The card is supported by drivers in Windows 11, 64-bit, operating system. The connection to the computer is through USB protocol.
