[3dem] carbon coating devices

[Ruben Diaz]

Hi David,

We have a spanking new one here at La Jolla Institute, so I cannot attest
to its reliability yet, but from my first two tries making the carbon, I
can tell you that the film releases beautifully from the mica sheets and
looks like a mirror. It is the nicest I have seen. In the microscope, the
film also looks super uniform and nice. Using the evaporator is very easy,
although the preparation takes a little longer than with a Cressington, for
example, or a Denton, and you need to have pretty steady hands for this
(don't drink too much coffee before doing it). The thickness monitor seems
to be spot on and the gadget looks gorgeous and shiny. We have the version
that also does sputtering, and you can do your glow discharge with it. On
the minus side, is the fact that it is rather pricey, and Leica parts (some
of which are consumables) are very expensive, but each carbon rod is
supposed to last for several shots.

Ruben,
