PicoQuant and Seven Solutions jointly release white paper on synchronizing TCSPC units in a White Rabbit timing network

Free paper demonstrates impact of synchronization on time accuracy of MultiHarp devices connected by switches

In a recent paper, researchers from PicoQuant have demonstrated that synchronizing Time-Correlated Single Photon Counting (TCSPC) devices in a White Rabbit timing network has only a negligible effect on their time accuracy. Multiple devices from PicoQuant’s MultiHarp product line were connected using Low Jitter White Rabbit switches from Seven Solutions the leading manufacturer of White Rabbit components. The authors have investigated how various network topologies, optical fiber lengths, and presence of Ethernet traffic affects the time accuracy of connected MultiHarp 150 and MultiHarp 160 devices.

PicoQuant improves the MultiHarp 150’s temporal resolution

Latest firmware and software updates improve the temporal resolution to 5 ps for the high-throughput multichannel event timer

PicoQuant is releasing a free firmware update for several models of its MultiHarp 150 high-throughput multichannel event timers. A major feature of this update is the improvement of the temporal resolution from 10 to 5 ps for the MultiHarp 150 4P, 8P, and 16P, without affecting other parameters like the excellent data throughput or the system's ultrashort dead time. Another new feature the update provides is a programmable input hysteresis for noise suppression in difficult environments. These MultiHarp 150 models provide the best temporal resolution on the market for event timers featuring sub-nanosecond dead time, which makes these devices an ideal choice of TCSPC electronics for fast and precise fluorescence lifetime imaging (rapidFLIM) and high throughput multichannel photon correlation.
