20 Jul 2009 PicoQuant announces an extended version of the multichannel Picosecond Event Timer and TCSPC system "HydraHarp 400" that can now accomodate up to eight independent input channels. Each channel is based on a novel time digitizer with 1 picosecond resolution, a processing rate of 12.5 million counts per second, a very short dead time and an extremely low differential non-linearity. The „HydraHarp 400“ is modular and can be fitted with 2, 4, 6 or 8 identical input channels and a common sync channel. This qualifies the instrument for advanced applications such as DOT. All channels operate independently, but with a common crystal time base. Therefore, not only TCSPC histograms but also picosecond coincidence correlations across all channels can be obtained. The latter is of great interest in single molecule work and quantum information processing research. |
