GENERAL HISTOLOGY

Detailed explanation-1: -The higher the power of magnification, the smaller the field of view. For example, if you determine that your field of view is 2.5 mm in diameter using a 10X ocular and 4X objective, you will be able to determine what the field of view will be with the high power objective by using the above formula.

Detailed explanation-2: -In short, as magnification increases, the field of view decreases. When looking through a high power compound microscope it can be difficult to determine what you will see through the eyepieces at different magnifications.

Detailed explanation-3: -The 4x objective lens has the lowest power and, therefore the highest field of view.

Detailed explanation-4: -The lower the eyepiece’s magnification, the higher the field number; for example, a 10x will have a field number between 16 and 18 millimeters on average, but a 5x will be around 20 millimeters.
