TECH FOCUS: SINGLE-PHOTON COUNTING Sponsored by Hamamatsu Photonics FEATURED PRODUCT
Photon Counting Modules (SPCMs) are self-contained modules that meet the low- light-level detection demands of confocal microscopy, fluorescence, luminescence, and TCSPC, particle sizing and quantum communications. Hamamatsu Photonics
manufactures and customises multi-pixel photon counter (MPPC) detectors and modules in-house, using its silicon foundry technology. MPPCs, otherwise known as SiPMs, are a semiconductor photon- counting device made up of multiple avalanche photodiode (APD) pixels operated in Geiger mode.
ID Quantique offers a
range of quantum sensing products and solutions. For single-photon detection, there are single-photon avalanche diodes in the visible wavelengths (Si, 350-900nm) and telecom wavelengths (III-V material, 900-1700nm), as well as the high-efficiency, broadband and picosecond- fast superconducting nanowire devices (780-1625nm). Pacer is a distributor of photon-counting solutions from Excelitas, including SPCMs with high single-photon detection efficiency, and greater sensitivity than the PMT in the visible range. APDs are also available that are designed to provide higher sensitivity than standard photodiodes. Photek’s IPD3 is based on a true single-photon counting sensor that provides simultaneous position and timing information for each detected photon. The camera outputs a continuous stream of photon detection location and time (x, y, t), with a spatial resolution of 100µm and a timing resolution of 10ns. The IPD3 is ideally suited for continuous imaging of processes with very low light levels over wide fields. Photon Force manufactures

counting cameras and sensors. The company’s technologies are used in areas such as photonics, quantum optics and scientific/engineering research, bringing order-of-magnitude acceleration to single-photon imaging and data processing. The company also provides a range of custom sensors and camera firmware as needed, where non-standard functionality may be required. Photon Lines supplies
radiation detectors and imagers from Advacam for academic and industrial use. Advacam commercialises Medipix technology, which is currently under development at CERN, Switzerland.
Photonic Solutions is a significant partner distributor for Becker & Hickl, offering the full range of TCSPC cards and multichannel scalers within its photon-counting equipment product range. Pi Imaging Technology was established to change the way light is detected by creating photon-counting arrays with high sensitivity and low noise. Its technology is based on seven years of dedicated work at TU Delft and EPFL and six patent applications. The core of it is a single-photon avalanche diode (SPAD) designed in standard semiconductor technology. This enables the photon-counting arrays to have an unlimited number of pixels and adaptable architectures. Princeton Instruments’
ProEM-HS:1024BX3 is a EMCCD camera, using low- noise readout electronics and a 1,024 x 1,024 EMCCD. This camera delivers single- photon sensitivity and fringe suppression with patented eXelon3 technology. The 2-in-1 camera features 30 MHz readout speed with the EM gain mode to deliver 25fps, a slow scan normal clock- induced charge (CCD) readout mode with very low read noise for precision photometry applications.
Detector and camera solutions for single-photon counting Hamamatsu Photonics provides a comprehensive range of single-photon detectors that cover all technologies from Single- Pixel Photon Counter (SPPC) and Multi-Pixel Photon Counter (MPPC, also known as SiPM) to PMTs. It also offers a range of scientific cameras, including the latest groundbreaking ORCA- Quest 2 qCMOS photon number resolving scientific camera. Its MPPC detectors employ multiple APDs (Avalanche Photodiodes) and operate in Geiger mode, detecting wavelengths ranging from VUV to NIR. They operate at low voltage and offer high gain, high photon detection efficiency, rapid response, excellent time resolution, low afterpulse, and low noise. The ORCA-Quest is the world’s first camera that achieves the
ultimate in quantitative imaging by photon number resolving, enabled by unique electronics with a market-leading low readout noise. Building upon the success of its predecessor, the ORCA- Quest, the new ORCA-Quest 2 offers exceptional performance and versatility. It features faster readout speeds in extremely low-noise scan mode, and increased sensitivity in the UV region. The new model remains the only CMOS camera on the market that enables precise quantification of photoelectrons.
