Scanning Electron Microscopy (SEM): SEM is a powerful surface microscopy method which allows for high resolution images to be obtained on a wide range of samples. A focused beam of electrons sweeps across a sample surface and an image is created from the scattered electrons. The electron beam allows for the accurate imaging of features below the resolution limit of visible light. The acquired pictures retain good depth of field, resulting in excellent three-dimensional images. Variations in beam parameters can be made in order to highlight variations in density in the target sample, show extremely fine surface features, and illustrate texture in sample surface coatings. MicroVision Labs has three fully-operational SEMs, Bruker X-Flash EDS detectors and mapping technology, backscatter electron (BSE) imaging, variable pressure and large chamber capabilities, providing a full suite of microscopy services for all of your analytical needs.
