The HARPIA-TB is a third beam delivery module for the HARPIA-TA unit that adds an additional dimension to time-resolved absorption measurements. It allows multi-pulse time-resolved spectroscopic techniques, in which the ongoing pump-probe photodynamics are perturbed by a delayed third pulse.
Combining TCSPC and MCS data acquisition in one electronics module enables a lifetime range that extends over twelve orders of magnitude, from a few picoseconds to seconds. Sample: DASPI in ethanol Excitation Source: 375 nm pulsed diode laser (EPL-375) Counts Time …
TCSPC module determines the time of the photon within the laser pulse sequence and the location within the scanning area. These values are used to address the histogram memory in which the events are accumulated. Thus, in the memory the distribution of the photon density over the scan Aurea Technology is launching the SPD_AT, its new near-infrared time-correlated single-photon-counting (TCSPC) module. The ultralow-noise and high-quantum-efficiency 900- to 1700-nm device includes a Geiger-mode InGaAs avalanche photodiode and thermoelectric coolers that ensure high detection efficiency of up to 25%. The TCSPC Module for Superconducting NbN Detectors. Fastest Member of the SPC-150N Family; Time Channel Width Down to 203 fs; Electrical Time Resolution 1.1 ps RMS ( < 3 ps FWHM ) Extremely High Timing Stability, Low-Frequency Timing Wobble < 0.4 ps RMS; Ideal for Superconducting NbN Detectors; 10 MHz Saturated Count Rate The Principle of Time-Correlated Single Photon Counting Time-resolved fluorescence spectroscopy is a pow-erful analysis tool in fundamental physics as well as in the life sciences. Implementing it in the time do-main requires recording the time dependent inten-sity profile of the emitted light upon excitation by a Announcement SPC-180NX – 28 Years of TCSPC/FLIM Experience.
The TCSPC module receives the timing pulse, the PMT channel number, and the scan clock signals (frame sync, line sync and pixel clock) from the scanning unit of the microscope. For each photon, the TCSPC module determines the location within the scanning area (x and y) and the time of the photon in the laser pulse sequence (t). Based on FPGA fast electronics, the CHRONOXEA TCSPC correlation module features a high transer rate up to 1 x 106 correlations/sec. In addition, it offers a PC connection via its USB interfaces.

The CFDs not only reject noise and low-amplitude pulses but also prevent the amplitude jitter of the detector pulses from inducing timing jitter. The principle of a CFD is shown in Fig. 3. FIG. 3. TCSPC originates from the measurement of excited nuclear states and has been used since t Our store has a featured set of products; not all products are shown.
