Study Notes

Microscope Components and Their Functions

Total Magnification is the product of the magnifications of the ocular lens and the objective lens being used.
Example: Ocular lens (10x) and objective lens (40x) result in a total magnification of 400x.

Microscope Image Quality

Resolution (Resolving Power) is the ability of a microscope to distinguish two points as separate.
Higher resolution results in a clearer image and better detail.
