Application of electron microscopy TEM and SEM for ...

Jul 01, 2019  An electron microscope uses a particle beam of electrons instead of visible light to illuminate the specimen and produce a magnified image. Because electrons have de Broglie wavelengths about 100,000 times shorter than visible light, electron microscopy can achieve 0.05 nm resolution and magnifications of up to about 10,000,000x.
