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.
