Stereo microscopes are used for observing larger, opaque objects that require a three-dimensional view, like insects, minerals, or electronic components. By using separate optical paths for each eyepiece, they create a stereoscopic (3D) image, providing excellent depth perception. With a lower magnification range and a greater working distance than compound microscopes, they are essential for dissection, quality control, and any task that involves manipulating a specimen under magnification.
