An optical microscope is a scientific instrument that uses visible light and lenses to magnify small objects, making them easier to see. It typically consists of an objective lens and an eyepiece, which work together to enlarge the image of the specimen. Optical microscopes are commonly used in laboratories, schools, and medical settings to study cells, tissues, and other tiny structures. These microscopes can achieve magnifications of up to 1,000 times, allowing users to observe details that are not visible to the naked eye. They are essential tools in fields such as biology, materials science, and medicine, helping researchers and students explore the microscopic world.
