Quantum X litho is the world’s first system for Two-Photon Grayscale Lithography (2GL®), designed for the fabrication of 2.5D, or planar, micro-optics. This maskless lithography process provides ultra-smooth freeform surfaces with exceptional shape accuracy, all in a single, high-throughput fabrication step. From Fresnel lenses for focused illumination to microlens arrays and hybrid optics combining refractive and diffractive features, Quantum X litho expands the scope for prototyping, mastering and wafer-level production of advanced 2.5D optical designs.
