Microscope Magnification

What will you be able to see under a high power microscope?

 

When using a high power microscope (also known as a compound microscope) it is best to start out with the lowest magnification, get your specimen in focus, and then move up to the higher magnifications one at a time. This is the easiest way to ensure that you will be able to focus in on your object quickly. At 400x magnification you will be able to see bacteria, blood cells and protozoans swimming around. At 1000x magnification you will be able to see these same items, but you will be able to see them even closer up. Below is a list of your field of view at different magnifications. Field of view is how much of your specimen or object you will be able to see through the microscope.

 

  • At 40x magnification you will be able to see 5mm.
  • At 100x magnification you will be able to see 2mm.
  • At 400x magnification you will be able to see 0.45mm, or 450 microns.
  • At 1000x magnification you will be able to see 0.180mm, or 180 microns.
