SensL Photon Counting and Timing Systems

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 PCD Mini

SensL PCDMini

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.

SensL HRM Time-TDC

SensL HRM Time-TDC

 

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.
