3D Printed Gradient Index (GRIN) Lenses

3D Printed Gradient Index (GRIN) Lenses are additively manufactured through 3D inkjet-printing. These gradient optics are printed from two polymer inks containing nanoparticles and then cured to hold shape. By changing the nanoparticle concentration during the manufacturing process, a gradient refractive index is created in the optic which can be designed to vary in any axis. The 3D inkjet-printing process is capable of altering the refractive index contrast, refractive index gradient, and chromatic dispersion of the produced lenses, enabling highly complex or freeform optical functions. 3D Printed Gradient Index (GRIN) Lenses are used in defense applications, including night vision systems and imaging systems for unmanned aerial vehicles, to create smaller, lighter optical systems.
