Detailed explanation-1: -The objective lenses come in 3 or 4 magnifications and can be turned to change the lens. The total magnification of the sample is calculated from multiplying the magnification power of the eyepiece lens with that of the objective lens in use. Eyepiece x10 and objective x40 gives x400 magnification.
Detailed explanation-2: -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-3: -How much bigger does it look? The magnification is a measure of how much bigger an image appears than the actual size of the specimen. If the objective lens has a magnification of x40 and the eyepiece lens x10, the overall magnification would be x400.
Detailed explanation-4: -The same principle apply to stereo microscopes, a 10X eye piece combined with a 4X objective lens will produce 40X magnification. Some stereo microscopes equipped with continues zoom objective lens with magnification from 0.75X-7.5X. The total magnification will be 7.5X to 75X when combined with 10X ocular lens.
