What are the pros and cons of an electron microscope?

Table of Pros and Cons
Scanning Electron Microscope
+ large depth of field allows more of a specimen to be in focus at one time
+ uses electromagnets rather than lenses so the researcher has much more control in the degree of magnification.
+ strikingly clear images
– unable to produce colour

What are the disadvantages of compound microscope?

Cons:
  • The magnifying power of a compound light microscope is limited to 2000 times.
  • Certain specimens, such as viruses, atoms, and molecules can’t be viewed with it.

What is a limitation of the electron microscope explain why this is a limitation?

What is a limitation of using TEM electron microscopes to view specimens? … Preparation of cells for TEM requires fixation (with chemicals or cryotechniques) that can introduce artifacts and damage. The preparation of cells/tissues for TEM is lengthy. TEM relies on highly sophisticated and expensive machinery.
