Electron Microscopy
The
main
point
of Electron
Microscopy is
the
unusual
short
wavelength
of
the
electron
beams,
substituted
for
light
energy.
The
wavelengths
of
about
0.005
nm
increases
the
ressolving
power
of
the
instrument
to
fractions
of
a
nanometer.
It
makes
it
possible
to
see
viruses
and
larger
molecules
clearly.
Two
types
of
electron
microscopes
are
in
use
today:
