TCSPC modules and External Markers Step 1: Know the marker signals Check the documentation of the scanner controller or contact its manufacturer to Step 2: What does the TCSPC module expect?

Sample: DASPI in ethanol Excitation Source: 375 nm pulsed diode laser (EPL-375) Counts Time (ps) 0 2000 102 103 1 10 Residuals 0-3.7 3.7 1000 The TCSPC method is often thought to suffer from slow recording speed and long measurement times. This bad reputation comes from traditional TCSPC devices built up from nuclear instrumentation modules which had a maximum count rate of some 104 photons per second. State-of-the-art TCSPC devices from Becker & Hickl achieve count rates of Instrumentation Recording of time-resolved fluorescence images was achieved by combining a confocal laser scanning microscope (Zeiss LSM-510 Axiovert), a femtosecond Coherent titanium sapphire laser and an SPC-730 time-correlated single photon counting (TCSPC) imaging module developed by Becker & Hickl, Berlin. ID220 Single-Photon Detector Module TCSPC at Wavelengths from 900nm to 1700nm We describe picosecond time-resolved optical signal recording in the spectral range from 900 nm to 1700 nm.

The second and third modules measure the relative propagation times, tx Consequently, if the detection efficiency is to be increased, the largest potential is in the optical system, not in the detector or in the TCSPC module. Nevertheless, The TCSPC module (SPC-130EM, Becker&Hichkl, Berlin, Germany) counted a fluorescence photon each second and calculated the lifetime using the NIM signal Compact TCSPC filter based system capable of measuring lifetimes from 100ps to s.

The SPC-130-EMN is a small size and low-cost time-correlated single photon counting ( TCSPC) module (patented) with high-time resolution for standard fluorescence lifetime applications and for applications requiring a large number of parallel TCSPC channels.

Its advantages, when compared to the TCSPC are twofold: a) the short time required for data acquisition; and b) the higher sensitivity of the … Single-Photon Counting Modules are self-contained modules that meet the low-light-level detection demands of confocal microscopy, fluorescence, luminescence, TCSPC, particle sizing and Quantum Communications. Time-Correlated Single Photon Counting (TCSPC) is a widely used technique to gather insights into fluorescence lifetimes on the ps and ns timescale. To study different molecular building blocks and materials, a short-pulse excitation source with high, but variable repetition rates, and an adjustable excitation wavelength in the visible and near-infrared (420-840 nm) is required. functionalities of several electronic devices into a single and flexible one: time-tagger, TCSPC module, delay generator, digital conditional filters and counters. A comprehensive, affordable, versatile and scalable series of instruments composed of 3 different main versions: 2014-01-15 The bh HPM-100 module combines a Hamamatsu R10467-40 GaAsP hybrid PMT tube with the preamplifier and the generators for the PMT operating voltages in one compact housing. The principle of the hybrid PMT in combination with the GaAsP cathode of the R10467-40 yields excellent timing resolution, a clean TCSPC instrument response function, high detection quantum efficiency, and … Diode laser modules are available in a wide variety of wavelengths, output powers, beam shapes and with a variety of electronic functionality and form factors. Wavelengths from 405nm laser to 1300nm laser are available with maximum output power up to 2W.

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 PicoHarp 300 is a high-end, easy to use, plug and play Time-Correlated Single Photon Counting (TCSPC) system. It is connected to a PC through a USB 2.0 interface.

TCSPC is a sensitive technique for measuring fluorescence decays on nanosecond time scale and longer. The principle of TCSPC is based on the precise registration of the arrival time of fluorescence photons from a sample.

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 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).
