Concave and convex lens
Concave and Convex Lenses are essential optical components used to manipulate light by refraction. A convex lens is thicker at the center and converges light rays to a focal point, while a concave lens is thinner at the center and diverges light rays. These lenses are fundamental in various scientific experiments, optical instruments, and educational demonstrations to study image formation, focal length, magnification, and light behavior. Manufactured with high-quality optical glass or plastic, they offer clarity and precision necessary for laboratory and industrial applications.
