Silicone-on-glass (SOG) diffractive optical elements (DOE) for the correction of chromatic aberrations and lens shape

Abstract

Chromatic aberrations are limiting the imaging performance of lenses. The classical way to correct of chromatic aberrations using flint and crown glasses adds volume, surfaces, and cost to the optical system. We present a novel approach to the problem based on diffractive optical elements (DOE) which can be applied as thin layers of silicone on glass substrates. We explain the optical design, the tooling required for highly efficient DOEs and the manufacturing process.
