Photon counter C16531-GD series

analogindustrialhigh-sensitivity

1 ch SPAD module (for VIS to NIR region) The C16531 series is a photon counting module that can detect low-level light. These modules consist of a thermoelectric cooled single photon avalanche diode (SPAD), an amplifier, a comparator, a SPAD bias circuit, and a temperature controller. The photosensitive area is available in two sizes of φ50 μm and φ100 μm, and such small photosensitive areas offer a low dark count. These modules operate by simply connecting to an external power supply (±5 V). Features - Single photon counting is possible. - High sensitivity in the long wavelength range - Low dark count - Low afterpulse Specifications • Wavelength type : VIS to NIR • Built-in sensor : SPAD • Effective photosensitive area : φ50 μm • Spectral response range (min./max.) : 400 to 1000 nm • Dark count (typ.) : 20 cps • Photon detection efficiency (typ.) : 65 % • Output : Digital • Measurement condition : Ta=25 ℃, λ=λp, Vs=±5 V
