[400 nm - 1060 nm] Time-Correlated Single Photon Counting Module: LynXea_VIS - Auréa Technology

The LynXea_VIS from AUREA Technology is a stand-alone [400-1060 nm] Time Correlated Single Photon Counting TCSPC module, which fully integrates the Time to Digital Converter and the best single photon avalanche detection (SPAD) counting technologies within the same box. As a matter of fact, TCSPC measurements are now available without assembling multiple boxes!

AUREA Technology provides the LynXea a new generation of all-in-one, high-performance and easy-to-use Time Correlated Single Photon Counting (TCSPC) modules. The LynXea is ultra-low-noise and high quantum efficiency single photon TCSPC module with timing resolution in the 60 ps range. The TCSPC module from AUREA Technology is proposed in two versions, the LynXea_VIS_M1 with 1 channel and the LynXea_VIS_M2 with 2 independent channels. This newly designed TCSPC module enables the growth of new applications, such as for example in fluorescence spectroscopy, photo-luminescence and coincidence measurements for Qauntum information technologies.

TDC

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

Correlation between the trigger signal (trigger the laser) and the photon detector APD1,
Correlation between the trigger signal (trigger the laser) and the photon detector APD2,
Cross-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.
