ULTRA-HIGH RESOLUTION TRANSMISSION ELECTRON MICROSCOPE UHR-TEM - LIBRA® 200 MC
UHR-TEM LIBRA®200MC/Carl Zeiss GmbH is used for atomic and micro-scale investigations in materials science of solid and soft materials (e.g. polymers). Combining the well-established LIBRA® 200 platform with state-of-the-art aberration correctors provides powerful new atomic-scale imaging and analytical capabilities. Improved resolution and chemical sensitivity give access to developing next-generation applications in additional fields such as life sciences, semiconductor and nanotechnology. UHR-TEM LIBRAâ 200 MC is equipped with monochromator, energy filter in column, image corrector, EELS (Electron Energy Loss Spectroscope), EDS (Energy Dispersive X-ray Spectroscope) and Lorentz lens. The working modes are: UHR-TEM, HAADF (High Angle Annular Dark Field), EELS, EFTEM (Energy-Filtered Transmission Electron Microscopy), EDS, SAED (Selected Area Electron Diffraction), precession diffraction, and STEM (Scanning Transmission Electron Microscopy).
