Fiber coupling type 1 ch SPAD module (for VIS to NIR region) The C16533-050GD is a fiber coupling type photon counting module that can detect low-level light. It consists of a thermoelectric single photon avalanche diode (SPAD), an amplifier, a comparator, a SPAD bias circuit, and a temperature controller. The module operates by simply connecting to an external power supply (±5 V). Features - Fiber coupling type - Single photon counting is possible. - High sensitivity in the long wavelength range - Low dark count Specifications • Wavelength type : VIS to NIR • Built-in sensor : SPAD • Effective photosensitive area : - • Spectral response range (min./max.) : 400 to 1000 nm • Dark count (typ.) : 20 cps • Photon detection efficiency (typ.) : 45 % • Output : Digital • Note : Fiber coupling type • Measurement condition : Ta=25 ℃, λ=630 nm, Vs=±5 V
