Here we study aspheric phase pattern geometric-phase lenses through thedesign of doublet lenses in Zemax Optic Studio and in MATLAB using a simple raytracing code. The solutions developed use variable spacer distances and aresolved monochromatically (at 633 nm) and polychromatically (at 450, 532, and633 nm). After selecting a Zemax generated polychromatically optimized doubletsolution, we fabricated the lens utilizing liquid crystal films and directwriting. We characterized the liquid crystal alignment quality, efficiencies,and spot performance of this lens in comparison to a standard spherical singletof the same back focal length and diameter (24.5 mm diameter and 40 mm backfocal length at 633 nm). With this aspheric lens profile, we realize thedevelopment of novel focusing phase surfaces.
