compound lens

A compound lens is a system made up of multiple individual lenses combined to work together. Each lens has a shape that bends (or refracts) light to focus it more accurately than a single lens could. By using several lenses, a compound lens can correct distortions and improve image clarity, giving a clearer and sharper view. This design is common in eyeglasses, microscopes, and cameras, where precise focusing and image quality are important. Essentially, combining lenses allows for better control over how light is directed, resulting in clearer, more accurate images.
