Optical instruments are devices that use light to enhance our ability to see objects. Common examples include microscopes, which magnify tiny details, and telescopes, which allow us to observe distant celestial bodies. These instruments often use lenses or mirrors to focus light and create clear images. In addition to microscopes and telescopes, other optical instruments include binoculars for viewing distant scenes and cameras for capturing images. Each of these tools relies on the principles of optics, the study of light and its interactions with various materials, to function effectively and provide valuable visual information.
