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.
