A form of microscopy that uses a beam of electrons (instead of light ) to scan the surface of objects. It is used to examine very fine particles and is at least 20 times more powerful than the light microscope.
Instrumentation used to observe minute surface details of small organisms/objects at high magnification by means of electron lenses. SEM techniques are often employed and needed to correctly identify a dinoflagellate species.
a microscopic technology that produces images at resolutions measured in microns.
produces high resolution images of the morphology or topography of the sample surface by imaging the electrons reflected when the sample is scanned with an electron beam. Monitoring the secondary X-rays produced by the electron-sample interaction using energy dispersive spectroscopy for element identification allows compositional analysis.
is a scanning method, which utilizes a microscope with 200 times magnification or greater.
