FIRST IN PHOTONICS
The ID110 brings a major breakthrough for single photon detection at visible wavelengths in demanding conditions.
Conventional single-photon detectors based on Silicon Avalanche Photodiodes (APD) are typically operated in free-running mode. Their performance can be strongly impacted by intense optical pulses. The detector is blinded by the intense pulse due to the dead-time effect occurring after each detection. This deadtime can extend to 100’s of ns. In addition, the charges trapped in the APD junction, as a result of intense optical pulses, increase the noise level, potentially masking the signal of interest.
The ID110 Gated Visible Single Photon Detector brings a solution to these problems by operating the APD in GATED MODE. The bias voltage is kept below breakdown to deactivate the detector and enhance trap discharge, except when detection is specifically enabled.
Contrary to other products on the market, which simulate GATED MODE by controlling the activation of the output avalanche signal (also called post-gating), the id110 operates in real GATED MODE at high-speed (internal or external trigger) frequencies up to 100MHz and offers the best discrimination performance. Photons can be detected with probability up to 25% at 530nm, while maintaining low dark count. A timing resolution lower than 200ps can be achieved.
