In classical EM, the cathode is
above and the beam is directed
downward. In the LVEM5 the FEG
cathode is at the base of the
microscope and travels upwards
towards the YAG scintillator.
In contrast to classical
architecture, the electron optic
column is very short, making up
only ~ 50% of the LVEM5 height.
The new operating console allows
a great degree of comfort as the
operator is free to operate the
system and observe results via
the monitor, away from the
microscope body.
The LVEM system is built on a clever
inline platform of
optics:
Electron optics:
provide initial image
formation via the
electron beam, capable
of providing structural
detail in the scale of a
few nanometers
Light optics:
stable and reliable,
classical light optics
are the perfect tool to
magnify the image on the
YAG screen to workable
dimensions.
Digital Imaging:
the digital camera,
mounted on the top of
the LVEM5 captures the
magnified image from the
light optics for image
capture and analysis |

All in all, the LVEM5 marks
a radical and fresh
departure from classical
electron microscope
architecture, a departure
that is welcomed by the
ambitious researcher.
