  • 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

    : cold cathode field emission electron source

    • Resolution

    - < 1.0 nm @15 kV

    • Magnification

    - LM 20 ~ 2,000 x, HM 100 ~ 800,000 x

    • Accelerate voltage : 0.1 ~ 30 kV (0.1 kV/step)

    • Electrical image shift : ± 12μm (WD = 8 mm)

  • Applications

    • Secondary electron image

    • Energy dispersive spectroscopy (EDS)
