Abstract
Optical components have a material-distribution gradient due to nanometer-size particles embedded in a solid matrix. The components are manufactured by forming a dispersion of nanometer-size particles in a liquid, curable matrix material, causing the particles to migrate in the matrix material on the basis of a potential difference to form a distribution gradient, and subsequently curing the matrix material, retaining the distribution gradient. The method is suitable for use in the manufacture of optical lenses with a refractive index gradient.
