Different Types of Microscopes By Ryezah
Dissection Microscopes Dissection Microscopes are light illuminated. The image that appears is 3-Dimensional. It is used for dissection to get a better look at the larger specimen. Dissection Microscopes have a low magnification so you can not see the individual cells on a specimen using it.
Compound Microscopes Compound Microscopes are also light illuminated. The image seen with this microscope however is 2-Dimensional. This is the most commonly used microscope. You can view individual cells, even alive ones. It has a high magnification, however a low resolution.
Scanning Electron Microscopes Scanning Electron Microscopes (or SEM), are electron illuminated. The image is seen in 3D. They have high magnification and high resolution. The specimen is coated in gold and the electrons bounce off to give you an exterior view of the specimen. The pictures are in black and white.
Transmission Electron Microscopes Transmission Electron Microscopes (or TEM) are also electron illuminated. This gives a 2D view. Thin slices of specimen are obtained. The electron beams pass through this. It has a high magnification and a high resolution.
