FORT LAUDERDALE/FL/USA, 06.08.2007.
Following a series of successful system installations at international evaluation and co- development partners, Carl Zeiss SMT officially introduces its world-wide unique monochromator module (MC) for its LIBRA® 200 kV TEM series systems. The highly innovative and patent protected ZEISS monochromator enables to reduce the energy width of primary electrons to less than 0.2 eV and thereby allows for highest resolution Electron Energy Loss Spectroscopy (EELS). The proprietary ZEISS monochromator combines this substantial reduction in electron energy spread with the capability to form a highly focused and especially bright spot in a unique way. Already installed LIBRA® 200 EFTEM systems can be retrofitted with the new monochromator module.
Outstanding analytical capabilities .
Especially when it comes to Electron Energy Loss Spectroscopy (EELS), the new monochromator module significantly improves the resolution of fine structures of elemental absorption edges. Combined with another proprietary module of ZEISS' high-end TEM series, the in-column Omega Energy Filter of the LIBRA® 200 EFTEM, this allows to fully exploit the enhanced elemental resolution by a simple push-button operation. Thereby, the monochromated LIBRA® 200 MC opens up new dimensions in compositional and structural analysis of advanced materials in all major disciplines of atomic-resolution analysis and characterization.
Intrinsic advantages of monochromated 200 kV accentuated
The rapidly growing adoption of corrector technologies for high-end TEM is not accidentally. In many applications users had to compromise between the destructive effects of high acceleration voltage and achievable resolution. This compromise is no longer necessary with corrector technologies becoming commercially available. Together with its partners, during the past years Carl Zeiss SMT's Nano Technology Systems Division has developed monochromator, corrector and energy filter technologies up to a daily-use, non-expert maturity state. Only recently the one-of-a-kind CRISP system (for Corrrected Illumination Scanning Probe) from Carl Zeiss SMT has been inaugurated at the research center caesar in Bonn (Germany). The CRISP system combines the new monochromator module from ZEISS with a corrector module to form the smallest available sample illumination spot, achieving unprecedented performance at monochromated 200 kV in Scanning Transmission Electron Microscopy (STEM) mode.
