Abstract

We report the fabrication of large, laser-formed refractive microlens arrays on doped borosilicate glass. Tuning the laser heat-source properties was found to give precise control over the melt process and the resulting lenslet geometries. Measurements of focal length, index, and surface shapes show excellent uniformity across these arrays.
