Hi Dale,
    Yes, I contacted them in the first place, as they have the best PMT
(in my opinion). But the APD they recommend me is really not good
(C5460) -- 2-3 times weaker signal than the PMT. I think APD should
perform better than PMT in 800nm region, and that's why many reflective
confocal setup uses APD (well, also APD should be cheaper).
