About

Johannes Lang is a pioneering researcher at the intersection of additive manufacturing and optical engineering, best known for his foundational work in the additive manufacturing of optical components. His highly cited 2016 paper (47 citations) established a critical framework for applying 3D printing technologies to optics, demonstrating that additive methods could move beyond mechanical parts to produce functional, high-precision optical elements. This contribution opened new design possibilities for freeform optics, enabling complex geometries unattainable through traditional grinding and polishing. Lang’s research has been instrumental in advancing the field of 3D-printed optics, influencing subsequent work on polymer-based lenses, waveguides, and micro-optical systems. His achievements highlight a transformative shift in optical fabrication, merging rapid prototyping with optical performance. For students and researchers, Lang’s work represents a key milestone in the convergence of manufacturing innovation and photonics, offering a compelling pathway for future developments in customized, lightweight, and integrated optical devices.
