Dear Markus thanks a lot for your comment. I've checked before and there is a good amount of signal at 750 with one of our halogen. I was going to try a led too. I'll see what will work better thanks again           -Claudio *************************************************** Claudio Vinegoni, Ph.D. Center for System Biology MGH-Harvard University Richard B.

Its spectrum in the IR is pretty good, better than most arc lamps. If you take out the heat filter (which is what removes the strong IR part of the spectrum), you will have plenty of IR. You can check out the spectrum here: http://zeiss-campus.magnet.fsu.edu/articles/lightsources/tungstenhalogen.html Regards Markus -----Ursprüngliche Nachricht----- Von: Confocal Microscopy List [mailto:[hidden email]] Im Auftrag von Claudio Vinegoni Gesendet: Freitag, 14.

Or alternatively a lamp that could be used in the range 600 up to 750? Checked Sutter and Exfo but they die pretty quickly at around 600 Thansk for any suggestion -Claudio
