Timing at Its Best: We`ll Count for You

In time-correlated single photon counting (TCSPC), single photons are not only counted, but the time of detection is also determined based on a reference signal. Here, a laser pulse generally serves as a reference. This method is a statistical counting method.

TCSPC is used in particular in fluorescence lifetime measurements. This method is often compared to a stop watch: A laser pulse excites a sample (time start); just a few pico or nano­seconds later, a “fluorescence photon” is released (time stop). This time is recorded in a histogram. After many start-stop passes, a conclusive histogram is created that displays the intensity of the fluorescence depending on time.

The COUNT® T is equipped with an avalanche photodiode (active area of 150 µm) produced in house and features a high detection ­efficiency of >80% and a temporal resolution of up to 350 ps.
In addition to fluorescence lifetime measurement (FLIM), the timing module is used in time-resolved fluorescence and single-molecule spectroscopy, as well as LIDAR applications. The technical data of the COUNT® T is given in the datasheet, which can be downloaded under the link provided.
