The majority of light microscopes have an objective lens of some kind, which includes both compound microscopes and stereo microscopes. These types of microscopes are also the same in that each type has an eyepiece or ocular lens.
The objective lens and the ocular or eyepiece lens are in combination responsible for magnification of the specimen being observed.
For example:
Total magnification = Objective magnification X ocular magnification
Therefore, for 10X objective and 10X ocular the total magnification = 10 X 10 = 100X
This means that the specimen being observed is now 100X it’s actual size.
The majority of compound microscopes come with interchangeable objective lenses, which have different magnification powers. This commonly includes 4x, 10x, 40x, and 100x objective lenses.
As previously mentioned, the ocular or eyepiece lens is located at the top of the eyepiece tube and is where you position your eye to observe the specimen. The ocular lens typically has a low magnification (10x) and works in combination with the objective lens to achieve a greater magnification power.
The objective lens is at the bottom of the eyepiece tube and is responsible for both total magnification of the specimen, as well as the resolving power of the microscope.
