The device is optimized for applications requiring up to 64 timing channels with a time resolution of 5 ps and ultra-short dead time of <650 ps. All TCSPC modules provided by PicoQuant expect standard TTL pulses for the external markers. This means 2-5 V for a logic “high”-level and 0-0.8 V for a logic “low”-level. For more info about TTL signals see here. The basic concept of this measurement mode is to record every individual photon of a TCSPC experiment. Both the arrival time as well as the TCSPC timing information (i.e. the time from the preceding excitation pulse or to the following excitation pulse in reverse start stop experiments) are recorded.

The PicoQuant TimeHarp 200 TCSPC board is a plug-and-play computer board with dedicated software.4,9 It occu-pies one PCI slot. One SMA connector receives the SYNC signal from the laser diode driver. In our case, the photon signal si.e., the SPAD’s outputd is fed directly to the Time-Harp’s START input through a 20 dB inline rf attenuator. The MultiHarp 160 is designed for applications requiring up to 64 synchronized inputs without compromises in time resolution and data throughput PicoQuant is known for a fast and qualified support to its customers. We will help you with all your requests related to the usage of our instruments or our software as quickly as possible.

TimeHarp 260, count rates up to 40 Mcps can be achieved.

kcps. Oldfashioned NIM based TCSPC electronics can handle a maximum of 50,000 to 500,000 cps. With modern integrated TCSPC designs count ra-tes over 10 Mcps can be achieved.

.. DPH-PC was excited by a 378 nm PDL 800-D pulsed diode laser and emission was recorded at 430 nm. The MultiHarp 160 is designed for applications requiring up to 64 synchronized inputs without compromises in time resolution and data throughput PicoQuant has quite a few treats in store for attendees of this year’s virtual SPIE Photonics West (March 6–11, 2021). A major highlight is the launch of the A new programmer's library is available for the PicoHarp 300 Time-Correlated Single Photon.

The fluorescence lifetime imaging and correlation software now supports the eight-channel configuration of its HydraHarp 400 time-correlated single-photon-counting system (TCSPC) and, therefore, data acquisition and analysis for up to eight detection channels. PicoQuant Lifetime Upgrade Kit for PTI QuantaMaster (TCSPC), which is considered to be the most sensitive and accurate measurement method to determine fluorescence lifetimes with picosecond accuracy. The kit further includes picosecond pulsed diode lasers or LEDs, A new programmer's library is available for the PicoHarp 300 Time-Correlated Single Photon. Counting system from PicoQuant. The new library version 2.2 provides several new features, including driver support for the 64 bit versions of Windows Vista and fixes some minor bugs found in earlier versions.

It is also worth noting that the actual count arrival times of course are random so that there can be bursts of high count rate and periods of low count rates. Bursts of It contains the complete optics and electronics for recording fluorescence decays by means of Time-Correlated Single Photon Counting (TCSPC) and/or Multi-Channel Scaling (MCS). The system is optimized for high temporal resolution and can be used with femtosecond or picosecond lasers, like the picosecond diode lasers from PicoQuant. all PicoQuant TCSPC units include two fundamentally different Time-Tagged Time-Resolved measurement (TTTR) modes. The core idea of these T2 and T3 modes is to introduce an additional timing information that represents the time difference since the start of the measurement on an absolute scale.

With modern integrated TCSPC designs count ra-tes over 10 Mcps can be achieved.
