Apochromatic lens

An apochromatic lens is an advanced optical lens designed to reduce color distortions called chromatic aberrations, where different colors of light focus at slightly different points. By carefully combining special lens elements made of different types of glass, apochromatic lenses focus multiple wavelengths of light more precisely onto the same point. This results in sharper images with accurate color representation and less blurring or color fringing, especially at the edges. Such lenses are often used in high-quality photography, microscopes, and telescopes to achieve clearer, more true-to-life images.
