Micro-Channel Plate (MCP) Capacitive Division Imaging Readout (CDIR) detector for FLIM

The Photek Capacitive Division Imaging Readout (CDIR) detector, is a Microchannel Plate (MCP) vacuum detector that can detect photons with both spatial resolution and a very high timing resolution of the order of 100 ps. The CDIR detector, capacitively couples the charge output of the MCP electron multipliers on a readout geometry, which shares the collected charge between four readout nodes at each corner. The charge collected at each node is then measured using the NINO ASIC, a charge sensitive amplifier/discriminator, and the HPTDC ASIC, a high time resolution time-to-digital convertor, allowing the charge position to be calculated using a centroiding imaging algorithm. The system is currently been developed by Photek Ltd, Phil Birch and Roger Phillips of the Â鶹ӳ»­ Centre form Advanced Microscopy. A second arm uses camera for intensity imaging, results can be seen here.

The detector has been intergrated into our custom build SPIM () pictured below.
