Area of Science:

  • Materials Science
  • Engineering Education

Background:

  • Traditional scanning electron microscope (SEM) training requires dedicated, on-site access.
  • Limited availability and high costs of SEMs can hinder widespread educational use.

Purpose of the Study:

  • To develop an accessible and cost-effective laboratory for teaching SEM operation.
  • To enable remote learning and operation of SEMs using standard computer technology.

Main Methods:

  • A computer network facilitates remote SEM operation.
  • Movable teaching stations with computer, monitor, and joystick allow control of SEM parameters and image acquisition.
  • Internet connectivity enables access from any location.

Main Results:

  • Students can view SEM images, manipulate samples, control microscope parameters, and acquire X-ray spectra remotely.
