Schottky Electron Gun

Cornerstone of Your Electron Microscope

In industry or science, the customers sometimes need to build their own electron optic solution. We meet these needs with two types of standardized Schottky electron guns with universal application for custom solutions, such as:

  • Inspection and analytical electron microscopes
  • Lithographs and other devices
  • Customized Delong Instruments columns
  • Other electron optics solutions by Delong Instruments

Using LVEM saved me more than 2 hours per day! Even if my newcomers worked on it.
