In addition to being powerful scientific instruments, microscopes can also serve as valuable educational tools in a classroom setting. After all, there’s no better way to learn about the structure of minerals and biological specimens than by taking an up-close look at them. That’s why microscopes are common features of classrooms and home science labs all over the world. But before you invest in a microscope for educational purposes, it’s important to understand your options. Generally speaking, these microscopes fall into two broad categories: flat field and stereo microscopes.
Also known as compound microscopes, flat field microscopes utilize a single objective lens to magnify specimens on the stage. Flat field microscopes offer high viewing resolutions and magnifications, but they have a very narrow depth of field due to their single-lens design. As a result, flat field microscopes are only suitable for viewing very flat objects such as biological specimens on microscopic slides.
Stereo microscopes use two separate optical paths to achieve a much greater depth of field than their flat field counterparts. In essence, these microscopes mimic the function of our eyes, albeit at much higher magnifications. Because they allow us to perceive specimens in three dimensions, stereo microscopes are far more versatile than flat field microscopes. If you plan on studying anything other than biological specimens, a stereo microscope is the way to go.
