A compound microscope is an optical instrument that uses multiple lenses to magnify small objects. It typically consists of an eyepiece lens and one or more objective lenses, allowing for high levels of magnification. This type of microscope is commonly used in laboratories and educational settings to observe tiny specimens, such as cells and microorganisms. The design of a compound microscope enables it to achieve greater magnification than simple microscopes, which use only one lens. The light source, often located beneath the stage, illuminates the specimen, making it easier to see details. Compound microscopes are essential tools in fields like biology and medicine, aiding in research and diagnostics.
