Resumen/Abstract

Microlenses for extrinsic optical fibre sensors have been fabricated on fused silica using Ultrafast Laser-assisted Etching (ULAE) technique. Then the quality of a proof-of-concept manufactured microlens was evaluated by studying point-spread function profile and taking Airy disk as reference.
