Electron Microscopes

[P3D Paul S. Boyer <boyer@xxxxxxxxxxxxx>]

Dr. Dave asks:
"We are getting a used Transmitting Electron Microscope here at work
soon.
Could someone direct me to info about proper spacing for stereo
pictures?
Any other info on obtaining the best possible final product would be
greatly
appreciated - film, subject, angle of view, etc."

I don't think that you can make stereo with a transmission electron
microscope.  What you need is a scanning electron microscope (SEM).
Then you rotate the subject about 6-degrees between exposures.  Cut
out the images of the subject on the print paper and mount them on a
black background, or do same thing with PhotoShop.  Works
beautifully.

I don't think that a TEM has enough depth to work with.

That reminds me: last year I bought an SEM used for a ridiculously
low price.  Then I got cold feet, and sold it the next day.  They
take up room and require Au- or AL-coating of the subjects and
elaborate cooling.  I just didn't have the time to learn to run and
service the thing.  I still feel bad about this, because the SEM is
one of the most marvelous devices of the century.  What a toy!
