Monocular microscopes belong to a microscope family, so-called "high power microscopes" (for its large amplification) or "compound microscopes" (for its mechanism of multiple objective lens). They are used to look at the tiniest things such as insect parts, plant parts, blood cells, yeast cells and even bacteria! Most have three lower objective lenses giving total powers of 40X, 100X and 400X. Some have a fourth lens offering 1000X (!). Monocular microscope has only one eyepiece lenses at the top. But some have two eyepiece lenses (binocular head). Stereo microscopes are also called "inspection", "dissection" (for its widely used functions in biological or medical laboratories) or "low power" microscopes. They are often used to look at relatively large things. Both binocular microscopes and stereo microscopes have two eyepieces. However, unlike binocular microscopes, stereo microscopes have its own objective lens for each of their eyepiece. Therefore, you will see the object in 3-D or "stereo" under stereo microscope.
