What is the Comparison between zone plate and convex lens?

Oh, what a lovely question! A zone plate is a unique optical device that can focus light similar to a convex lens, but it uses diffraction rather than refraction. Both the zone plate and convex lens can converge light to a focal point, creating images and patterns, each with its own beautiful characteristics. Just like in painting, it's all about exploring different tools and techniques to create something truly special.
