Fast metasurface hybrid lens design using a semi-analytical model

Abstract

We propose a new method for integrating metasurfaces in optical design using semi-analytical modeling of dielectric nanostructures. The latter computes the output phase of an electric field incident on the metasurface, allowing their use with ray-tracing software. This tool provides a method to use metasurfaces in optical systems while using built-in optimization processes to avoid time-consuming computation. To demonstrate the applicability and versatility of our method, we present variations of a triplet composed of refractive elements and a metasurface. For each of the systems, similar optical performances are achieved. Our unique and innovative approach to joining metasurfaces and ray-tracing has the potential to promote the design of innovative systems by exploiting the richness of metasurfaces and the functionality of conventional lens design software.

Realization of a cost-effective 3D-printed lens for aberration correction for visible spectrum imaging

“…In a Cooke triplet design, five Seidel aberrations are removed with the help of three glasses separated by air [7][8][9][10]. The triplet design also consists of a flint glass and a crown glass [11][12][13]. The triplet has a flint glass in the middle, acting as a concave lens (negative element), whereas the crown glass, acting as a convex lens (positive element), comes at both sides [14][15][16].…”
