What is it about?
This review explores a cutting-edge 3D printing technique called Two-Photon Polymerization Lithography (TPL) and its potential in making tiny, complex lenses for imaging devices. Traditional glass lenses are made using complicated processes, but with the increasing demand for smaller, more advanced optical systems, new methods are needed. TPL allows us to create extremely small and detailed structures using a special laser technique, making it possible to build tiny lenses directly from liquid resin with high precision. This process could revolutionize how we make lenses for cameras, microscopes, and other imaging tools, leading to smaller, more powerful devices.

Why is it important?
Our review provides an overview of the latest advancements in TPL and its applications in the field of optical imaging, offering a foundation for researchers and helping to drive future innovations in lens design and manufacturing.
Perspectives
I see this publication as not only a comprehensive review but also a call to action for researchers to explore and embrace the vast potential of TPL in revolutionizing optical imaging. The integration of this technique into mainstream optical fabrication could lead to a new era of high-performance, miniaturized imaging systems that push the boundaries of what's possible.
