MICROANATOMY

Detailed explanation-1: -To get the total magnification level you must multiply the magnification of the ocular lens by the magnification of the objective lens. So, if you are viewing your slide under the 40x objective lens you would multiply that by the 10x of the ocular lens for a total magnification of 400x.

Detailed explanation-2: -Grades 1-8 typically will buy a monocular compound microscope with 3 objective lenses: 4x, 10x, 40x for maximum total magnification of 400x.

Detailed explanation-3: -The total magnification of a typical compound microscope with 10x eyepiece and 4x, 10x, 40x, 100x objectives will be 40x, 100x, 400x and 1000x depending on the lenses used. The same principle applies to stereo microscopes.
