Search the CONFOCAL archive at http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal I also noticed that Hamamatsu has some applications literature that might be of interest: for APDs: http://sales.hamamatsu.com/assets/applications/SSD/Characteristics_and_use_of_SI_APD.pdf and also other detectors: http://sales.hamamatsu.com/en/support/technical-notes.php Again, I have no connection with Hamamatsu, but thank them for making good technical information available!
