Abstract

Refractive lenses that offer color correction over a wide spectral range often rely on a complex design with multiple elements to reduce chromatic aberration. In this work we demonstrate a two-element lens design with achromaticity spanning the visible to the mid-infrared. The air-spaced doublet designed from commercially available materials show significant reduction in spot size and chromatic shift compared to single lens alternatives. The lenses were tested on a beam-scanning sum-frequency generation (SFG) microscope to validate the improved optical performance. Though standard practice is to use reflective components for ultra-broadband applications, limitations in performance, particularly at off-axis field angles, provide merit for the use of broadband refractive focusing optics.
