Aspherical optics or aspherical lenses are optical components that have a non-spherical surface profile. Unlike traditional lenses that have a curvature that follows a specific mathematical shape, such as a sphere or cylinder, aspherical lenses have complex surface profiles that can correct for various aberrations and improve the overall optical performance of a system. Aspherical optics are used in a wide range of applications, including camera lenses, eyeglasses, telescopes, and microscopes, where image quality and resolution are critical. Research in this area focuses on developing new fabrication techniques, modeling and simulation methods, and applications of aspherical optics in various fields. The goal of this research is to create more compact, lightweight, and high-performance optical systems for a diverse range of applications.
