An optical system is a collection of optical components that work together to manipulate light in various ways. These systems can include lenses, mirrors, and other elements designed to focus, magnify, or disperse light, enabling the creation of images or the enhancement of vision. Common applications of optical systems are found in devices like cameras, microscopes, and telescopes, which rely on precise arrangements of these components to function effectively. The design and performance of an optical system depend on the principles of geometric optics and wave optics. By understanding how light behaves when it interacts with different materials, engineers can create systems that meet specific needs, such as improving image clarity or increasing light sensitivity.
