Freeform Optics Design Approach Uses Starting-Point Geometries

Facebook X LinkedIn Email
Researchers have developed a step-by-step design method for determining which freeform surfaces will work best in a given configuration. The new method, which combines theory and practice, could eliminate the time-consuming, expensive process of using trial-and-error to determine which freeform surfaces will best achieve the desired result. The method developed at the University of Rochester’s Center for Freeform Optics (CeFO) starts with the initial “folding geometry” (alignment of mirrors and lenses) for an optical design and then, based on an analysis of the various...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...
