A stereo zoom microscope is an optical microscope designed for low magnification observation of a sample using two separate optical paths, providing a three-dimensional (3D) view. It consists of a pair of eyepieces, objective lenses, and a zoom mechanism that allows continuous variation of magnification without refocusing. The microscope offers a wide field of view and high depth of focus, making it ideal for examining the surface details of solid specimens. Commonly used in biology, electronics, and material sciences, it is particularly useful for dissection, circuit inspection, and quality
