At the Microscopy and Microanalysis Meeting and Exhibition being held in
Albuquerque, New Mexico, Carl
Zeiss SMT is introducing a major upgrade of its LIBRA® 120 Energy Filter
Transmission Electron Microscope (EFTEM).
Libra® 120 PLUS is an upgrade which is a complete redesign of the microscope's vacuum system.
The primary focus of the upgrade was a complete redesign of the microscope’s
vacuum system – taking on frequent requests from customers and users.
Thus the constantly increasing demands in revealing structural and 3-D information
of beam sensitive or frozen hydrated samples at a nano scale can be matched.
Complementary the range of magnification has been extended and an additional
illumination mode, called „wide field illumination“ has been developed.
The completely dry, TMP based, new vacuum system excells through a sophisticated
three step field-upgrade path, allowing customers to adapt the system to growing
needs. Complemented by a highly flexible detector concept this energy filtering
TEM is an extremely versatile instrument in all areas requiring ease of use,
high throughput and a broad range of applications. In particular many new applications,
e.g. from the field of life science and soft matter, where advanced vacuum conditions
are required can now be addressed.
The integrated Koehler illumination system guarantees minimum beam damage,
reproducible illumination conditions, permanently homogeneous and strictly parallel
beam with exactly quantifiable dose rates. Invented by ZEISS, this concept is
recognized as state of the art for light and electron microscopes.
The lifetime factory-aligned in-column OMEGA energy filter improves image contrast
by completely eliminating chromatic aberrations. It provides a seamless integration
and extends the LIBRA® 120 PLUS to a fully analytical TEM enabling STEM,
EDS, ESI and EELS.
