Optical Instruments

Optical instruments are devices that manipulate light to enhance our vision or capture images. They work based on principles of optics, particularly geometrical optics, which studies how light behaves when it travels through different materials. Common examples include glasses, microscopes, and cameras. These instruments use lenses and mirrors to focus or redirect light, allowing us to see objects more clearly or magnify small details. By understanding light’s path, optical instruments improve our ability to observe the world around us, making them essential in fields ranging from medicine to photography and astronomy.
