Summary: | Femtosecond laser direct writing achieves high precision into micro-metric in
additive manufacturing of customized-geometric structures and was used to fabricate the high
quality micro optical lenses in various photoresist, including SU-8, by two-photon polymerization.
The fabricates axicons could approximately create the Bessel beam, which has smaller beam
diameter and extended depth of focus, so that widely employed in imaging systems. The axicons
and any geometric micro-lenses of certain applications were designed and optimized using
ZEMAX before the lenses being fabricated by femtosecond laser direct writing, and they serve as
core components of imaging systems, microscopy, and other research fields. |
