Photon counting solutions

In photon counting experiments such as Hanbury Brown-Twiss setups, a common challenge is synthesizing and presenting data to detect coincidences or compute g²(𝛕) and higher-order correlation functions, prolonging project timelines. The Moku Time & Frequency Analyzer accelerates data interpretation efficiency with real-time, lossless histograms and interval statistics for live computation of quantum statistics.

Adapt to different photon counting experiments

Reconfigurable Moku devices integrate an entire suite of instruments crucial for single-photon detection and analysis, like the Time & Frequency Analyzer, Phasemeter, and Lock-in Amplifier. Combine instruments in Multi-instrument Mode for system-level characterization and feedback control.

Log photon arrival times for post processing

Log detection intervals and event timestamps at up to 10 Mevnt/s for post-processing with the embedded Data Logger. Classify photons, measure the photon coincidence count rate to extract the second-order correlation, and monitor background signals to extract only meaningful information.

Analyze interval statistics in real time

Statistics like number of counts and mean, minimum, and maximum interval durations are computed in real time so you can view results while adjusting measurement parameters.

View real-time, lossless histograms

Make cumulative measurements to view how many intervals fall in a particular bin without lengthy post-processing data manipulation.

Generate live histograms

Using the Time & Frequency Analyzer, you can watch histograms accumulate with a minimum bin-width of 0.78 ps while performing experiments like time-correlated single-photon counting (TCSPC). Determine fluorescence lifetimes, photon count distribution, and measure g²(𝛕) functions in real time. Not sure how to configure your setup? View the configurations to get started.
