Light microscope

A light microscope is an optical instrument used to observe objects too small to be visible to the naked eye. It uses visible light and a system of glass lenses to create a magnified image. The basic principle is that a beam of light from a source passes through the observed specimen, which is placed near the first lens called the "objective." This lens creates the first magnified image. This image is then observed through a second lens, the "eyepiece," which acts like a magnifying glass and provides the final magnification for the observer's eye. Light microscopes are used to examine biological specimens such as cells, tissues, or microorganisms. For light to pass through the specimen, it must usually be very thin and translucent, often prepared on a special slide. For opaque materials, such as metals, a method is used where light reflects off the surface of the specimen. Besides magnification itself, a key property of the microscope is its resolving power, which is the ability to distinguish two points located very close to each other. This ability is physically limited by the wavelength of light, which is why a light microscope cannot display details smaller than approximately 200 nanometers.
