Hi all,
After several years break from the list I'm back on with an old
question that is perpetually new. It is:

What are people's recent multiphoton/confocal imaging experiences with new
detectors like the hybrid photodetector (e.g. H8236 PMT/APD) from
Hamamatsu or the new silicon PMTs (e.g. from SensL)? They seem to have
nice fast responses and the gains are getting better (10^6 for the
latter). Are PMTs still the popular choice?

Related question: What bandwidth for PMT analog I-V conversion is
required for fast scanning? Is 200KHz okay or does one need > 1MHz?
Or, are you using photon counting instead of analog, these days?

My two incentives for asking are: 1) I'm trying to keep my external
detectors alive a bit longer on our ancient BioRad 1024MP and 2) I'm
working on setting up another system. 

Thanks,
Brian O'Rourke
