An electron microscope is a microscope that uses beams of electrons instead of rays of visible light to form highly magnified images of tiny areas materials or biological specimens. Comparing light vs electron microscopes is made more complicated by the fact that there are different types of electron microscopes.
a TEM microscope privides an detailed image of the inside of a specimen a SEM microscope provides a 3D image of a specimen take for exampel a sperm in a TEM microscope you would see the inner stucture of the sperm in a SEM microscope you would se in detail the exact form shape of the sperm
No, a light microscope uses focused light (photons) to produce a magnified image. An electron microscope uses beams of electrons to create a magnified image.
The source of radiation of a dissecting microscope is light. The illuminated light is what will cause the image to appear in three-dimensional format.?æ
Light microscope: 1. Uses a beam of light that is focused using glass lenses. 2. Magnification is moderate -- not as much as electron microscope 3. Produces a color image since it uses light 4. Can look directly at the specimen with our eyes Electron microscope 1. Uses a beam of electrons that is focused using magnets. 2. Magnification can be extremely high and show details that are not possible with the light microscope 3. Produces a grey-scale image because color requires visible light 4. Image must be seen on a monitor or in a photograph because we don't see electrons.
There are three types of basic microscopes: Electron Microscopes, Simple Light Microscopes, and Compound Light Microscopes. Simple [light] Microscopes work by focusing light through one lens. The most common lens, the Convex Lens, works by being thicker in the center than the edge. This bends the light, altering the image as it hits the second lens, your retina. A Compound [light] Microscope works differently. It is the most common microscope for everyday use, using a mirror to shine light up through a slide containing a specimin. Next, the ray of light shines up through a series of lenses, bending the light and multiplying the magnification and resolution levels of the image, until it hits your retina. Robert Hooke used a very complex compound microscope to observe cells through a thin slice of cork wood. The Electron Microscope is the most technologically advanced and, in my opinion, the coolest type yet. In fact, the electron microscope was so complex that it was not discovered until the late 1930's. It uses a beam of electrons instead of light to magnify an image. This allows you to get a much closer image with much higher resolution than with a regular light microscope. The most complex light microscope can only magnify an image up to 5000 times. An electron microscope can easily double that, a recently founded electron microscope can magnify an image up to 150,000 times. To work, this microscope actually borrows electrons from atoms, and as long as they return the electrons to the atoms, there is still perfect balance.

A light microscope is a simple microscope that magnifies light that it collects and spread onto a screen digitally or optically. Electron microscopes is a microscope that fire electrons onto a object then it is bounced back to form an image. It enlarges the image when it is bounced back. It is fired consistently to receive a constant image. It is viewed with a electronic screen. When the electron is fired it creates light which bounces back as well. It can magnify much bigger than a optical microscope.
A compound light microscope is named for the use of more than one lens to collect and focus light, and magnify the image.
