Optical instruments harness light to enhance human vision, enabling observation and analysis from space to microorganisms. They rely on principles like reflection, refraction, and interference, and are characterized by refractive index, focal length, and aperture. These tools are essential in fields such as scientific research, industry, and healthcare, with applications ranging from eyeglasses and cameras to spectrophotometers and microscopes.
