Emerging applications of optical technologies are driving the development miniaturised light sources, which in turn require fabrication matching micro-optical elements with sub-1 mm cross sections and high quality. This is particularly challenging for spatially-constrained biomedical where reduced dimensionality required, such as endoscopy, optogenetics, or implants. Planarisation a lens by Fresnel approach was adapted conical (axicon) made direct femtosecond 780 nm/100 fs laser writing SZ2080™polymer photo-initiator. Optical characterisation positive negative fraxicons presented. Numerical modeling fraxicon performance under illumination incoherent spatially extended sources compared ideal case plane wave illumination. Considering potential rapid replication soft polymers resists, this holds great promise most demanding technological applications.
