- It’s important to understand the basic principles of the wave/particle properties of visible light, which is one small section of the electromagnetic spectrum. Electrons also have both wave and particle-like properties, so many of the principles that underlie electron microscopy are similar to those that underlie light microscopy.

Electron microscope focuses a beam of electrons through the specimen or onto its surface. Resolution is inversely related to the wavelength of the light (or electrons) a microscope uses for imaging, and electron beams have much shorter wavelengths than visible light.

Light microscopy uses lenses to focus light on a specimen to produce an image. Commonly used light microscopes include brightfield, darkfield, phase-contrast, differential interference contrast, fluorescence, confocal, and two-photon microscopes.
Oct 13, 2017 · Light microscopy has several features that make it ideally suited for imaging biology in living cells: the resolution is well-matched to the sizes of subcellular structures, a diverse range of available fluorescent probes makes it possible to mark proteins, organelles, and other structures for imaging, and the relatively nonperturbing nature of ...

Apr 21, 2024 · Visible light consists of electromagnetic waves that behave like other waves. Hence, many of the properties of light that are relevant to microscopy can be understood in terms of light’s behavior as a wave. An important property of light waves is the wavelength, or the distance between one peak of a wave and the next peak.
