MERLIN with the GEMINI II column and FEG electron source offers high resolution imaging using advanced detection modes, including InLens (SE), InLens (EsB), Angle Selective back-scattered detector (AsB), 3DSM and STEM. Gemini II optics imaging setting such as voltage or probe current can be adjusted without realignment. Parallel on-axis in-lens secondary electron (SE) and energy selective backscattered (EsB) detection can easily identify smallest differences in materials composition.
