Divide the focal length of the objective lens by the focal length of the eyepiece.
Multiply the power of the eyepeice by the objective lense
By multiplying the magnification of the eyepiece by the multiplication of the lens.
One can calculate the total magnification of a microscope by multiplying the magnification of the eye piece by the magnification of the main scope. For a compound microscope one must multiply each eye piece magnification.

Multiply the magnification of the eyepiece - by the magnification of the object lens. For example - if the eyepiece is labeled 10x, and the object lense is 12x... then the total magnification is 120x
the power of the ocular lens multiplied by the magnification of the objective lens
To calculate magnification , multiply mag.Power of both lenses 15 x 30 = 350
Field diameter of lens B equals field diameter of lens A times total magnification of lens A divided by total magnification of lens B
you multyply the low powered objective and the high powered objective :)
you multyply the low powered objective and the high powered objective :)
The total magnification is equal to the magnification of the eyepiece multiplied by the magnification of the objective lens. So in this case the objective lens would need to be 100X.
you multyply the low powered objective and the high powered objective :)
The general formula for Total maginifcation Tm is: Tm= Me x Mob where Me is the magnification produced by the eyepiece and Mob is the magnification produced by the objective.
eg. If the lens piece you are looking through is X10 and the objective lens is X100 it would be x1000
