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 SuperBandTM Optic, is ultimately explored in its functionality to address this need in an advantageous manner.
