Total magnification refers to the cumulative magnifying power of a microscope, which is derived by multiplying the magnification of the objective lens with the magnification of the eyepiece.

What Is Total Magnification
The total magnification of the microscope is calculated from the magnifying power of the objective multiplied by the magnification of the eyepiece and, where applicable,. To determine the total magnification of an image viewed through a microscope, multiply the power of the eyepiece or ocular lens by the power of the objective lens. Calculating total magnification for microscopy involves multiplying the magnification levels of objective and eyepiece lenses.
