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.


Cheers

Cam

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!
