Time Tagger Series

Streaming time-to-digital converters

Swabian Instruments' Time Taggers are streaming time-to-digital converters with a unique data processing architecture that makes them the preferred choice for Time-Correlated Single Photon Counting (TCSPC), time-interval counting, coincidence counting and digital protocol analysis.

The New Standard in time-correlated single photon counting.

Swabian Instruments' Time Taggers are used in a large range of disciplines, including quantum technology, single molecule microscopy, fluorescence correlation spectroscopy, dynamic light scattering, laser ranging, particle physics, and precision time protocol (PTP) testing. Browse the Time Tagger Series' documentation and application notes to find out how a Time Tagger can solve your measurement challenges.

Implement your ideas within minutes

What makes our Time Taggers unique is their powerful software engine that offers extensive data processing capabilities. Correlations, single- and multi-dimensional histograms, multi-order coincidence rates - it's all right there and it all runs live! You will implement your demanding research ideas within minutes - promised.

Maximum flexibility

The Time Tagger Series enables you to run measurements independently using any combinations of your input channels. You can even use a single Time Tagger to take data simultaneously from independent physical setups. Or you can run multiple measurements on the same channels at the same time.

High timing resolution

The low instrument jitter down to 4 ps RMS (9 ps FWHM) combined with best-in-class dead time down to 2 ns makes sure that you achieve highest timing resolutions in your application.

High data rate

The high streaming bandwidth of up to 65 M tags / s enables you to minimize your measurement time. The best: the Time Tagger will maintain its full on-the-fly processing capabilities at this high bandwidth.

Versatile on-board event filter

A unique on-board event filter enables you to increase the effective time tag rate way beyond the streaming bandwidth by filtering out unneeded time tags right on the hardware.

Native software libraries

Run your measurements in your preferred programming language with our free native software libraries and examples, covering Python, Matlab, LabVIEW, C#, C++ and Mathematica.

“Implement new research ideas more quickly“

Prof. Dirk Englund

Time Tagger 20 is enabling dramatically faster and more parallel digital data acquisition for my group. Its unique streaming architecture allows us to implement novel experiments with rather small coding efforts, thereby enabling us to implement our new research ideas very quickly.

“Very impressed, unrivalled flexibility and excellent value.“

Prof. Jason Smith

We have been very impressed with Time Tagger's specifications, unrivalled flexibility of use and excellent value for money. Swabian Instruments deserve considerable recognition not only for this innovative product, but for their user-oriented approach, and for their desire to develop instrumentation that will help to accelerate this field of research.
