What is the equation to calculate total magnification? Objective lens magnification x eyepiece magnification = total magnification
4X x X = X 10 n' 40
10X x X = X 10 n' 100
40X x X = X 10 n' 400
Objective Lens: 4X 10X 40X Total Magnification: 40X 100X 400X Width of Field of View (FOV): 4mm About 1.5mm About 0.4mm
