id220 Free Running SINGLE PHOTON DETECTION Module - NEAR INFRARED RANGE (900 - 1700nm)

The id220 brings a major breakthrough for single photon detection in free-running mode at telecom wavelengths. It is the first single-photon detection module built around an InGaAs/InP passively quenched avalanche photodiode. It provides a cost-effective solution for applications in which asynchronous photon detection is essential. The cooled InGaAs/InP avalanche photodiode and associated electronics have been specially designed for achieving low dark count and afterpulsing rates in free-running mode. The module can operate at detection probability levels of 10%, 15% and 20% with a deadtime that can be set between 1us and 25us. Arrival time of photons is reflected by a 100ns TTL pulse available on an SMA connector with a timing resolution as low as 250ps at 20% efficiency. A simple USB interface allows the user to set the efficiency level and the deadtime. A standard FC/PC connector with a single mode fiber or a multimode fiber (with a 62.5 microns core diameter) is provided as an optical input. The id220 comes with a +12V 60W adapter .

The detector is available with singlemode or multimode input
