Light microscopes are the most common piece of lab equipment in classrooms today. Modern microscopes use two lenses in a tube to magnify more than a magnifying glass. Lenses are found at both the eyepiece and the objectives. The two lenses combine the magnification to allow a sample to be magnified for detailed observation. A simple calculation is used to find the total magnification factor.
