A new Web-SEM system allows remote control of scanning electron microscopes via a web browser. This system overcomes internet traffic issues, enabling remote focus adjustment and stage movement for SEM operation.

Area of Science:

  • Materials Science
  • Microscopy
  • Computer Science

Background:

  • Remote operation of scientific instruments like scanning electron microscopes (SEM) is desirable for accessibility and collaboration.
  • Traditional SEM control often requires specialized software and on-site presence.
  • Internet connectivity and network traffic can significantly impact the performance of remote control systems.

Purpose of the Study:

  • To develop a novel remote control system for scanning electron microscopes (SEM) accessible via a standard web browser.
  • To ensure seamless and efficient SEM operation despite variable internet conditions.
  • To enable remote manipulation of SEM functions such as focus adjustment and stage movement.

Main Methods:

  • Development of the Web-SEM system, a browser-based interface for SEM control.
