A Compact, Robust, High Resolution TEM That is Easy to Use and Economical to Operate

Carl Zeiss SMT has introduced the new CENTRA™ 100 transmission electron microscope (TEM) at the 47th Annual Meeting of the American Society of Cell Biology in Washington D.C. The CENTRA 100 is a TEM with up to 100 kV accelerating voltage. Specially designed as a sophisticated “imaging system”, the highly compact and robust instrument offers maximum resolution down to 0.2 nm. The ease-of-use and fast specimen exchange capability make this microscope particularly well-suited for biomedical or clinical laboratory environments. It also features low operating costs, high specimen throughput, a very attractive price/performance ratio and low space requirements, thanks to the small footprint.

A key technical feature of the system is the choice between two different imaging modes: high resolution and high contrast. This is particularly important for investigating low-contrast biological specimens. The specially developed mini-lens design leads to a very compact size where the electron-optical lens elements exhibit only minimum aberration. The use of four lens elements in the projection system enables rotation-free imaging while the magnification is being changed. Furthermore, additional deflection systems support the image-fine-shift that enables the generation of panorama images.
