The Model DPC-1 Digital Photon Counting system includes a 'Plug and Play' PCI PC card and software.   It is a complete photon counting system that connects directly to photomultipliers having a TTL count output.  This photon counting system allows you to easily collect data directly from a photomultiplier into your computer.  This counting system simplifies the tools required to setup an ultra-sensitive light measuring instrument.  The DPC-1 PCI PC card is easy to install and is completely Plug and Play compatible.

The Model DPC-1 comes complete with our latest FluorMeasure^TM data acquisition software.  The software is Windows-based and is powerful, yet easy to use for fluorescence or other photometry photon counting measurements. The data can be saved in our own file format or as a "csv" file (comma separated value ASCII file) for easy import into other software applications.  Software "windows" can used to customize the viewing of your data.  

The Model DPC-2 is similar to the DPC-1, except that is has the added feature of analog data collection.   Up to eight channels of analog data can be acquired in synchronization along with the photon counting data.  A separate data window is used to view the analog data acquisition. 

Both the DPC-1 and DPC-2 systems can be easily upgraded for use with our Model S48D multiwavelength illuminator or Model D48 multiwavelength photon counting detector.  For a more general discussion of this product, refer to our Product Overview page.  To download the latest version of FluorMeasure^TM, go to our software page.
