http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Hi Folks, Not strictly a confocal question, but I am wondering if researchers are still purchasing traditional "video" cameras (i.e. Vidicon / Newvicon electronic imaging devices). My impression is that CCDs can now do everything the old-style video camera could do, and offer important advantages (such as quantum efficiency, linearity and dynamic range). But I am just wondering if there are any imaging niches where the tube style cameras are surviving? I would expect that many of these instruments are still in use-- they provided many great movies of living cells and organelles over the years! But are researchers still buying them? thanks for any comments, Don p.s. And I still owe the list a bibliography...which will hopefully emerge from the chaos of my life! Donald M.

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Hi Donald, I can see no need for anyone to purchase a older style video camera instead of a new CCD. The new CCDs have the features you mentioned, plus increased resolution and if you have the right camera an ability to capture data at high frame rates (to do full motion video). Though I can not think of many instances where you would need to capture anythign in real time. All the "movies" we do here are captured anywhere from 1 frame every minute to 1 frame every hour. That being said we still have a couple of scopes with older style video cameras on them (though I am pretty sure they are CCD based as well) that we use for demonstating disections on.

I think that people who are studying (intracellular) molecular dynamics will kindly disagree in this respect ;-) Why else are EMCCD camera's becoming so popular now? Some of them can go up to about 500 fps. Kind regards, Kevin Kevin Braeckmans, Ph.D. Lab.

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Dear, We agree with Kevin, our first impression with confocal was that the observed structures where quite immobile, but looking with a EMCCD we stated they were shaking as mad. So you cant conclude that the object stand still if you dont look at it in high speed.Nyquist criteria are needed for XY imaging but also for time sequences.
