Idea behind FLIM X16

The image acquisition time of a PMT based FLIM (Fluorescence Lifetime Imaging Microscopy) system is limited by its maximum photon counting rate that is typically between 1-8 MHz. FLIM systems that are based on intensified CCD cameras overcome this restriction – but sensitivity and spatial resolution in 3D microscopy applications is limited. LaVision BioTec‘s PMT based FLIM X16 TCSPC (Time Correlated Single Photon Counting) detector combines both advantages – it is fast and sensitive by using an PMT array of 16 channels and two 8-channel TDCs. These advanced electronics and detectors provide 76 MHz photon counting rate (short term bursts up to 2.5 GHz). Therefore, the FLIM X16 TCSPC is the perfect choice for laser-scanning microscopes.
