Leica Microsystems has introduced the Leica HyD SMD universal hybrid photodetector with characteristics for single-molecule detection, which allows precise measurement of concentration and observation of fast cellular processes. The photodetector combines the characteristics of the classic photomultiplier tube (PMT) with highly sensitive avalanche photodiodes, resulting in high sensivity and a large dynamic range combined with rapid detection speed and low dark noise. The photodetector is fully integrated into the spectral detection system of the Leica TCS SP8 confocal microscopy platform. An active cooling system comprised of built-in Peltier cooling and additional external cooling reduces the specified dark noise of the Leica HyD SMD, resulting in high-quality SMD data. The absence of detector afterpulsing give precise and reliable particle concentrations in FCS experiments, which short living dyes can be used to observe fast live-cell processes due to the fast instrument response time of the detector.
