KETEK release new generation of SiPM

KETEK, based in Munich Germany, are well-established as a supplier of CMOS-based SiPMs offering excellent performance in a rugged MSL1 qualified package and the new range of 3mm-only devices bring improvements in every key operating characteristic.

WL-Series SiPMs are available with three microcell pitches of 15µm, 35µm and 47µm - all offer performance enhancements compared with the previous WB-Series but are optimised respectively for Linearity/Saturation, Crosstalk and Photon Detection Efficiency. Key improvements offered by WL-Series SiPMs include:-

• High PDE; 51% (47µm microcell, 6.5V overbias)
• High Gain; 9.1M (47µm microcell, 6.5V overbias)
• Fast Recovery Time (Tau); (7ns, 15µm microcell)
• Industry-leading Saturation/Dynamic Range; 15µm
• Low DCR; 25kHz/mm² (15µm microcell, 2.5V overbias)
• Low Crosstalk; 4% (35µm microcell, 2.5V overbias)
• Low Afterpulsing; 1% at 2.5Vob
• Low Dark Current (max) ≡ DCR 45kHz/mm² (15µm microcell, 2.5V overbias)
• Low & Uniform Breakdown Voltage; 29.5±0.75V (±125mV per reel)

KETEK's Silicon Photomultipliers (SiPMs) surpass the current standard detectors (PMT, APD & PIN photodiodes) in many low light applications and are replacing these in a number of key applications areas such as:-

• Medical Imaging (PET, SPECT, CT)
• Hazard & Threat Detection
• LiDAR & 3D Ranging
• Biophotonics
• High Energy Physics
• Sorting & Recycling

SiPMs combine the benefits of vacuum PMTs (high photon detection efficiency, gain and signal-to-noise) with those of APDs (robustness, miniaturised design, low operation voltage, cost-effective and magnetic insensitivity) to produce an outstanding low level light sensor with exceptional performance at low cost.
