Our Achromatic Nanostructured Gradient Index (nGRIN) Microlenses, designed to revolutionize near-infrared imaging and beam manipulation. These microlenses boast achromatic correction across a broad spectral range (600–1550 nm), ensuring nearly wavelength-independent performance. Unlike traditional optics that suffer from chromatic aberrations due to the dispersive nature of glass, our nGRIN microlenses maintain a consistent focal plane, thanks to their uniquely designed internal nanostructure. With their simple, singlet element geometry and flat surfaces, these microlenses offer a simpler and more integrated solution compared to conventional aspheric doublets. Perfect for applications in dense wavelength division multiplexing systems, beam shaping, endoscopy imaging, and 3D imaging microsystems, our nGRIN microlenses open new perspectives for micro-imaging systems and wavelength-independent coupling into optical fibers.
