Lens design is the process of creating optical lenses that effectively manipulate and control the transmission of light in order to achieve specific imaging or focusing requirements. This field involves optimizing the shape, materials, coatings, and other properties of lenses to achieve desired outcomes in various applications such as cameras, microscopes, telescopes, and eyeglasses. Lens designers use advanced mathematical and computational tools to simulate and analyze the performance of lenses in different conditions and environments. The goal of lens design is to improve optical performance, reduce aberrations, and enhance overall image quality.
