Electron diffraction is an essential characterization tool for materials scientists. When using the transmission electron microscope (TEM) to perform diffraction experiments, setting up the microscope for both calibration standards and unknown materials in a consistent method ensures that dependable results are obtained. Care must also be exercised to protect digital cameras from intense transmitted and diffracted beams to avoid damage. In Parts 1 and 2 of this series, procedures were presented for recording high-quality, well-calibrated, digital SAED patterns. In Part 3, aspects of diffraction analysis software packages and the reliability of data are discussed.

The smartphone microscope, or mobile microscope, is an interesting tool that is attracting attention in various fields. We report a model of mobile microscope that extends from the Leeuwenhoek-type of single microscope with a simple lens. The new mobile microscope is called the “L-eye mobile microscope” and is compact and easy to handle. The L-eye mobile microscope may become a hobby tool in everyday life for people of all ages but may also be a tool suitable in the education of medical or paramedical students. To test its potential as an educational tool, its performance was examined using samples such as permanent specimens of tissue sections from several organs used in histology and a standard target for a microscopy resolution test. As a control, we used a conventional education-use microscope that is mounted with a smartphone for image capture. From the performance comparison of the two kinds of microscope systems, the L-eye mobile microscope could take images with almost the same quality as those obtained with the conventional microscope at moderate magnifications. This result suggests the usefulness of the L-eye mobile microscope for education.
