Light does not follow the exact straight path. The light microscope is an instrument for visualizing fine detail of an object. It does this by creating a magnified image through the use of a series of glass lenses which first focus a beam of light onto or through an object and convex objective lenses to enlarge the image formed. SEM provides detailed images of the surfaces of cells. Would have better if there was a box showing differences. Resolving power. Sometimes preparation of a sample may disturb the specimen. 4.5 / 5 based on 4 ratings. A number of differences such as the source of light they use, their magnification level, cost, resolving power, among other factors sets these two types of microscopes apart from each other. Electron Microscope On the contrary, an electron microscope has almost 1,000,000X magnification with a resolving power up to 0.

Electron microscopes uses short wavelength of electrons and hence have lower magnification. You made my entire semester by helping me to get started with valuable and informative helpful resourcing. The first electron microscope was constructed in 1931, compared to optical microscopes they are a very recent invention. thank you sooo much, this was very useful . Illuminating source is the beam of electrons. An electron microscope is an optical instrument that uses a beam of electrons to make objects larger for a detailed view. Electron microscopes have nothing to do with the wavelength of the radiation (thus the phrase effective wavelength), and thus produce grayscale (B/W) images. It is believed that Dutch spectacles makers. These cookies do not store any personal information. What game is Snake from Super Smash Bros from?

SEM focuses on the samples surface and its composition, so SEM shows only the morphology of samples. It has high cooling system in order to move out the heat generated by high voltage electric current. However, light microscopes are much more practical in general use. Most compound light microscopes produce flat 2D images because high-magnification microscope lenses have inherently shallow depth of field rendering most of the image out of focus.
