The quTAU Time-to-Digital Converter for Time-Correlated Photon Counting

11 May 2015

The quTAU records the timestamps of electrical signals, which is extremely important in time-correlated single photon counting.

The compact counter transmits the time an event occurs and the count rates of eight individual input channels via USB to a PC.  In addition, the quTAU exhibits a temporal resolution of 81ps.  The arrival times of the TTL incoming pulses are stored digitally and can be transferred to a PC using the USB 2.0.  The quTAU not only counts and stores individual events but coincidences between two or more channels as well. The coincidence time window can be easily set by the user.  All of the features have been designed with applications such as quantum optics, fluorescence microscopy, and high-energy physics in mind.

The system comes with example software for LabViewTM and C/C++ and can be operated on Windows^® and Linux PCs.
