SensL offers a solution for picosecond timing with ultra-fast detectors through the use of a 0.75 GHz Amplifier/Constant Fraction Discriminator (CFD) module.

The SensL CFD module comprises of two independent, fully programmable Constant Fraction Discriminators for interfacing with a wide range of detectors. The module setup parameters can be programmed via the USB or directly by the HRMTime using the sensL GUI or DLL drivers.

The TimeHarp 200 PC-board is a complete system for picosecond time resolved measurements, ideally suited for fluorescence lifetime measurements with thePDL 800-B as an excitation source. An integrated design keeps cost down, improves reliability and permits new applications. The system allows sustained measurement rates up to 3 million counts/sec and provides a time resolution under 40 ps. The system operates in reverse start-stop mode to allow synchronisation with fast laser sources. Both input triggers are programmable for a range of signal levels.

The PicoHarp 300 can be used in different operation modes: h-end, easy-to-use, plug and play Time-Correlated Single Photon Counting (TCSPC) system. It is connected to a PC through a state of the art USB 2.0 high speed interface. A new design approach provides identical and synchronized but independent input channels. They can be used as detector inputs for coincidence correlation experiments or as a pair of start and stop inputs for TCSPC. It allows a forward start-stop operation even at full repetition rate of mode locked lasers with stable repetition rate up to 84 MHz. Experiments with low repetition rate benefit from the PicoHarp's multi-stop capability. The design allows high measurement rates up to 10 million counts/sec and provides a highly stable, crystal calibrated time resolution of 4 ps. This time resolution is well matched to the SPADs of the PDM series or micro-channel plate photomultiplier tubes (MCP). Overall IRF widths down to 50ps can be achieved withpulsed diode lasers. With short pulsed lasers such as Ti:Sapphire lasers IRF widths as short as 30 ps can achieved. Both input channels are equipped with constant fraction discriminators (CFD), sensitive on the falling edge.

The HydraHarp 400 is a high-end, easy-to-use, plug and play Time-Correlated Single Photon Counting (TCSPC) system with scalability for multiple channels*. It is connected to a PC through a USB 2.0 high speed interface. It provides identical synchronised but independent input channels. They can be used as detector inputs for coincidence correlation experiments as well as independent stop inputs for TCSPC. A dedicated common sync input is provided for TCSPC with fast excitation sources. This allows forward start-stop operation at the full repetition rate of mode locked lasers with stable repetition rate up to 150 MHz. Experiments with low repetition rate benefit from the HydraHarp's multi-stop capability.

The core of all SensL detectors products are low light sensors which can convert low light, down to the single photon level, into a measurable signal. In photon counting the challenge is to convert this photon into an electrical signal and then count or time the arrival time of the photon.

Photon counting sensors are digital devices which can provide precise information on the number of photons arriving at the detector or the arrival time of the photon or both pieces of information as is required by the application.

SensL products in this area are the PCDMicro and the PCDMini which can be combined with SensL measurement instruments such as the HRMTime for the development of full photon counting and timing instrumentation. This represents a leading edge combination of performance, compactness and flexibility for system designers and OEMs looking to incorporate leading edge technology into their products.

SensL's PCDMini Photon Counting Device is the first miniature photon counting system on the market and features SensL's new quenching architecture with snap-on boards for enhanced functionality.

The sensor is hermetically sealed and comes with cooler board (for applications that require extremely low dark count) and a snap-on USB Interface Board which will significantly simplify the task of integrating the PCDMini into any measurement system. Its integrated counter functionality eliminates the requirement for a separate data acquisition system. DLL and LabVIEW drivers supplied with the USB Interface Board enable the user to easily integrate the module into their systems, while the compatibility with sensL's Integrated Environment (SIE) graphical user interface makes system monitoring and configuration extremely user friendly. This ease of integration, combined with the compact and miniature form factor of the product makes the PCDMini the ideal photon counting solution.

The HRMTime-TDC is the world's leading miniature low cost picosecond timing solution on the market. We have incorporated the latest time to digital converters to allow our HRMTime to provide picosecond timing across up to 4 channels. On top of this, the modular design and the use of USB data acquisition allows our users to build multi-channel system with multiple HRMTimes incorporated in them, quickly and easily.

We have optimized the HRMTime-TDC to work in quantum key distribution, fluorescence lifetime detection, time correlated single photon counting, and LIDAR laser range finding applications. The HRMTime is compatible with all of SensL detectors and any commercially available detector on the market such as PIN and APD photodiode, PMT and MCP detectors.  For additional flexibility and use with the widest range of detectors, sensL have introduced the sensL CFD which allows the HRMTime to precisely measure analog pulse signals.

For our OEM users, the HRMTime-TDC is provided as a low cost OEM component along with full DLL and LabVIEW drivers which can significantly decrease the time and effort required to incorporate high end timing into your products.
