Spherical gradient in refractive index (S-GRIN) lenses are lightweight and easily deformable, but manufacturing them with high quality and consistency is challenging. Now, researchers at the University of Rochester are embedding OCT into the manufacturing process to get a better view of the lens’ complete structure. “I had done the calculation and thought we could do it,” said Jannick Rolland, the Brian J. Thompson Professor of optical engineering at the university’s Institute of Optics. “And sure enough, after several months of work we had 3-D movies of the...Read full article

    freeform optics
    Freeform optics refers to the design and fabrication of optical surfaces that do not follow traditional symmetric shapes, such as spheres or aspheres. Unlike standard optical components with symmetric and rotationally invariant surfaces, freeform optics feature non-rotationally symmetric and often complex surfaces. These surfaces can be tailored to meet specific optical requirements, offering greater flexibility in designing optical systems and achieving improved performance. Key points about...
