The objective lens or mirror collects light and brings it to focus creating an image. Magnification = length of the Image divided by the Actual Length. Compound microscopes use two or more lenses to magnify the specimen. This is where the magnification calculation is necessary. The magnification of a microscope describes the increase in apparent size of an object compared with its actual size. How do you get the total magnification of an object? In other words, it tells us how much larger or smaller an image appears when compared to the actual object. Total magnification of an object observed through the eyepieces (ocular lens) is calculated by multiplying the ocular lens magnification times the magnification of the objective lens being used (either: 4X, 10X, 20X, 40X, 100X, etc.).
