"all-in-one" TCSPC module

AUREA Technology provides the LynXea a new generation of  “all-in-one” and easy-to-use near infrared Time Correlated Single Photon Counting (TCSPC) modules. The LynXea is ultra-low-noise and high quantum efficiency near infrared single photon TCSPC module with timing resolution in the 50 ps range. The TCSPC module from AUREA Technology is proposed in two versions, the LynXea_M1 with one channel and the LynXea_M2 for two channels. This newly designed TCSPC module enables the growth of new applications in the near infrared, such as for example in fluorescence spectroscopy, in photo-luminescence and coincidence measurements.

The SPD_AT_M2 from AUREA Technology is an "all-in-one" TCSPC module, which fully integrates the Time to Digital Converter with the single photon technologies within the same box.

LynXea_M2 TCSPC photon counter from AUREA Technology allows three diffferent possibilities of photon correlation, as follows:

• Correlation between the temporal trigger signal (trigger the laser) and the photon detector APD1,
• Correlation between the temporal trigger signal (trigger the laser) and the photon detector APD2,
• Temporal correlation between the photon detector APD1 and the photon detector APD2.

The TDC offers the possibility of measuring the arrival time of each detected photon relative to an excitation signal, such as a laser pulse, this within a time window (gate) selected by the user .

Following a repetition n, periodic excitation, the module records (accumulates) data corresponding to the time of arrival of each photon and displays a histogram of time (or curve). The width of the "time bin" of the histogram reflects the temporal resolution of the TDC and therefore the accuracy of the sampling time.
