optical microscope vs electron microscope

The wavelength ( λ ) of visible light falls within the range of 400–700 nm. Light sources commonly used in optical microscopes include arc-discharge lamps, incandescent tungsten-halogen bulbs, LEDs, and lasers. Aside from this wide difference in magnification capability, electron microscopes are said to project a more detailed field, compared to the fuzzy details of the optical microscope, that is especially noticeable at higher magnifications. Electron Microscopes use electrons and not photons (light rays) for visualization. Related terms * compound microscope * electron microscope * microscopic * microscopy * simple microscope See also * magnifying glass * telescope macroscope Not English Macroscope has no English definition. In scanning electron microscopy (SEM), due to the nature of electrons, electron microscopes have a greater depth of field compared to light microscopes. A SEM produces a beam of electrons with an electron gun. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century. Electron Microscopes vs. Optical (Light) microscopes, Observing bacteria under the light microscope. (false) Just to let you know, an advantage of a Transmission Electron Microscope over a Light Microscope is that you actually can observe living things, as otherwise detailed in your article. Cite -They are extremely expensive. to find out more information about the most incredible one of a kind Duel Scanning Electron Microscope and x-ray analyzer in the world (The Mini- Scanning Electron Microscope)! SEM provides a 3D impression of a specimen while TEM in contrast, gives a 2-dimensional cross section of a specimen.

Optical models are cheaper and easier to maintain than the electron microscope. This has a wavelength of about 400-700 nm (nanometer; 1 nanometer = 1 x 10-9 m). Generally, electron microscopes are better than its optical counterpart. The difference lies in their cost, effect on human health, resolution and the information they can obtain from a specimen. Thank you for giving these details. Overall, electron microscopes deliver a more detailed image compared to optical microscopes. Do your research, cite your sources and write your assignments using your own words. Electron Microscope has a resolution power greater than Optical Microscope which is 0.1 nm (nanometer). This is because the image delivered to each eye is slightly different. Dear, For more information
