This magnification value determines the diameter of the field of view when the low power objective is used. A microscope's field of view refers to the diameter of the circular optical light that is visible when viewing an object under the microscope. This value forms an inverse relationship with magnification, which means that increasing the magnification results in the reduction of the field of view.
Eyepiece Lens: The lens at the top of the microscope that you look into. They are usually 10X but also are available in 5X, 15X and 20X. Widefield lenses have a large diameter and show a wide area of the field of view. Fine Focus: This is the knob used to fine tune the focus on the specimen.
