The main purpose of a microscope is to magnify small objects or organisms that are not visible to the naked eye, allowing for detailed observation and analysis. Microscopes are vital tools in various fields, including biology, medicine, and materials science. By using lenses or electron beams, microscopes can enhance an object's appearance, revealing structures, textures, and properties that are crucial for research and diagnostics. Different types of microscopes, like light microscopes and electron microscopes, provide varying levels of magnification and resolution, catering to specific scientific needs.
