SEM – Scanning Electron Microscopy


Brand / Model

COXEM EM-30 Plus


Magnification: x20 – x150k (~ x80k)
Accelerating Voltage: 1kV to 30kV
Electron Gun: Tungsten Filament (w)
Detector: SE Detector, BSE Detector
Max. Sample Size: 45mm (H), 30mm (Diameter)
Vacuum System: Turbo molecular pump (less than 3min),
low vacuum mode


The SEM image is obtained by concentrating the high voltage accelerated electrons in the high vacuum environment on the sample, collecting
the products formed as a result of various interactions between the electron and sample atoms during the scanning of this electron beam
on the sample surface, and then transferring them to the screen as a result. Thanks to secondary electrons, a high resolution topographic
image of the sample is obtained. Furthermore, it is possible to analyze the insulating samples, polymers and glass samples that are not plated
with low vacuum mode.
It is used in researching the morphology of natural resources, determination of defects and wear properties of materials, determination of
properties such as surface properties of materials, coating thickness, particle size, morphology, etc.
