PicoQuant has released TimeHarp 260, a Time-Correlated Single Photon Counting and Multichannel Scaling board with PCI Express interface. It is based on a custom Time-to-Digital-Converter design that offers an ultra-short dead time and very high throughput even at high temporal resolutions. The system is available with either 25 ps or 1 ns base resolution. A timetagged mode allows the most sophisticated offline analysis of photon dynamics.
