Compound microscopes are optical instruments designed to provide high magnification and resolution for viewing small specimens such as cells, microorganisms, and thin tissue sections. They use a combination of two or more lenses—the objective lens (near the specimen) and the eyepiece lens (near the eye)—to magnify objects typically between 40x and 2000x.
These microscopes are widely used in biological, clinical, educational, and research laboratories due to their ability to reveal fine structural details invisible to the naked eye. Modern compound microscopes often include features such as LED illumination, mechanical stages, and digital imaging compatibility.
