Abstract

This article explores the complex design challenges of optical imaging systems that can operate over a broad range of the electromagnetic spectrum, covering all bands from the visible to the far infrared simultaneously. Although the focus is placed on a refractive solution to these challenges, an effort to outline the limitations of reflective solutions is also presented. After exploring a novel method to optimize the choice of optical materials, an elegant and efficient example is provided: a refractive lens that is at once a total optical solution (one lens covering a broad spectral range) and a common aperture solution (one lens that works simultaneously with several camera types). This solution, StingRay Optics' own SuperBand^TM Optic, is ultimately explored in its functionality to address this need in an advantageous manner.
