Photon counting at certain wavelengths in the UV, visible and near-IR range is one of the key technologies in today's fast-growing analytical instrumentation, diagnostics, and scientific applications space.
These Single Photon Counting Modules (SPCMs) are self-contained modules that offer market-leading photon counting performance in parameters like high Photon Detection Efficiency (PDE), low after pulsing, highest uniformity over active area, high linear dynamic range, and low dark counts. This series of single photon counting modules are designed and built to be fully RoHS-compliant.
The SPCMs we offer were the first APD-operated photon counting devices on the market. They use a unique APD that was developed specifically to be operated in so-called "Geiger-mode", which means operated above breakdown voltage, so that a single incoming photon triggers an avalanche of electrons already large enough to be detected and counted as an electronic pulse. The SPCM uses a unique silicon avalanche photodiode (SliKTM) with a circular active area intended for peak photon detection efficiency. The photodiode is both thermoelectrically-cooled and temperature-controlled, ensuring stabilised performance despite ambient temperature changes.Send Enquiry
