Scanning Electron Microscopy (SEM) Techniques

The history of the electron microscope dates back to early twentieth century when the first electromagnetic lens was developed. This opened the door of possibility to use the principles of the

How to clean a Transmission Electron Microscope without

Electron microscopes use a beam of electrons instead of light to make an image. The reason you can get more magnification with electrons is that they have much shorter wavelengths than light particles, which helps when you are trying to make an image of something. If you use an electron microscope to look at cells, you would see a lot more detail, like this:

I decided to design and build a scanning electron microscope (SEM) in my home workshop to see if it was even possible. Spoiler alert: it is. I didn’t originally intend to create an SEM that could compare to a $75,000 entry-level commercial model, but the project turned out more successful than I expected.

Electron Microscope Principle Components Specimen

An electron microscope uses electrons to visualize nano objects. The electron gun in an electron microscope, is large because you have to accelerate the electrons before you illuminate the sample with a beam of electrons, and all that running around requires some space.

All About the Electron Microscope

For those who want to use one at home, a USB electronic microscope is an option. While these are not as powerful as lab versions, they allow users to explore the microscopic world around them by uploading images to their computers. If you are enticed by the microscopic world, shopping the large inventory on eBay for a scanning electron microscope is a great way to open up your eyes to science.

You can't see DNA unless you look properly Stephen Curry

In 1933 a primitive electron microscope was built that imaged a specimen rather than the electron source, and in 1935 Knoll produced a scanned image of a solid surface. The resolution of the optical microscope was soon surpassed.

You can't see DNA unless you look properly Stephen Curry

Light Microscope vs Electron Microscope Both light microscopes and electron microscopes use radiation (light or electron beams) to form larger and more detailed images of objects (e.g. biological specimens, materials, crystal structures, etc.) than the human eye can produce unaided.
