Thick lenses are integral to optical design, featuring two principal planes and a significant thickness affecting light refraction. These lenses are essential in high-precision devices like microscopes, cameras, and telescopes, and are distinguished from thin lenses by their ability to provide higher magnification and control over light paths. Understanding their behavior, guided by fundamental equations, is crucial for optical engineering and applications in various scientific fields.
