Stereo microscope, is a specialized optical instrument designed for three-dimensional viewing of objects at low magnification levels. Unlike compound microscopes, which use a single objective lens, a stereo microscope employs two separate optical paths, providing a binocular view. This enables users to perceive depth and details of solid objects,.

Stereo microscopes are often used to study the surface of solid specimens or for close-up work, such as dissection, microsurgery, watchmaking, circuit board manufacturing or inspection, as well as fracture analysis and fracture surfaces in forensic engineering. With its versatile applications, a stereo microscope is essential for tasks that require accurate, up-close examination in a three-dimensional context.
