    • Description
    SEM is a microscope that uses electrons instead of light to form an image. The SEM uses electromagnets rather than lenses, the researcher has much more control in the degree of magnification. Field-emission scanning electron microscope provides ultra high resolution image down to 1 nm resolution thanks to the inherent brightness of field–emission electron gun.

  • Specifications

    • Electron gun

    : Schottky type thermal FE gun

    • Resolution

    - < 1.2 nm @30 kV high vacuum mode

    - < 1.5 nm @30 kV low vacuum mode

    - < 1.5 nm @30 kV ESEM mode

    • Beam current : > 100 nA

    • Heating stage (1,500 ˚C)

    • Cooling stage (-20 ˚C)

  • Applications

    • High vacuum mode

    • Low vacuum mode (10 to 130 Pa)

    • ESEM mode (10 to 4,000 Pa)
