Tutorial on Two Photon Lithography Tool
Online Presentations | 26 Nov 2018 | Contributor(s):: Mohammad Mahfuzul Kabir, Varun Ajit Kelkar
Two-photon lithography (TPL) is a nano-scale 3-d fabrication technique. TPL depends upon the two-photon polymerization process, whereby two incident photons of light are absorbed by a precursor material leading to polymerization. The smallest feature size (voxel) achievable in a TPL...
