A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning it with a focused beam of electrons.

If you've ever seen an electron microscope picture, you'll see this.

Two years later, in 1933, Ruska built an electron microscope that exceeded the resolution attainable with an optical (light) microscope.

Compound microscope A compound microscope is a microscope which uses a lens close to the object being viewed to collect light (called the objective lens) which focuses a real image of the object inside the microscope (image 1).

Reflection electron microscope (REM) In the reflection electron microscope (REM) as in the TEM, an electron beam is incident on a surface but instead of using the transmission (TEM) or secondary electrons (SEM), the reflected beam of elastically scattered electrons is detected.

And, secondly, to convince you that every home really ought to have a scanning electron microscope.

In 1927 he became the leader of the electron research group there, where he and his co worker, Ernst Ruska, invented the electron microscope in 1931.

All these pictures were taken with a scanning electron microscope, actually in the lab at Kew Laboratories.

As I say, every home should have a scanning electron microscope to be able to see these.

And under the scanning electron microscope, you can see the surface there really quite different from the other surfaces we looked at.

Optical configurations There are two basic configurations of the conventional optical microscope the simple microscope and the compound microscope.

And when we think about the classic image of the scientist in the lab, we have this image you know, they're pouring over the microscope, and they see something in the tissue sample.

And actually, you fill one electron here, another electron here, then another electron there.

Electron microscopy shows that the basement membrane consists of three layers the lamina lucida (electron lucent), lamina densa (electron dense), and lamina fibroreticularis (electron lucent).

While fluorine, that ninth electron just needs one more electron.

The rise of fluorescence microscopy drove the development of a major modern microscope design, the confocal microscope.

Types Microscope The objective lens of a microscope is the one at the bottom near the sample.

The stereo microscope should not be confused with a compound microscope equipped with double eyepieces and a binoviewer.

If you just go straight from the electron configuration, you would expect carbon, so the 1s orbital fills first, so that's our first electron, our second electron, our third electron. Then we go to our 2s orbital, That fills next, third electron, then fourth electron. Then you would expect maybe your fifth electron to go in the 2px.
