Fabrication of glass microlens array using laser-assisted contactless hot embossing
Contactless hot embossing is one promising replication-based method for fabrication of high quality microlens array (MLA) with different sag height but suffers long thermal cycle. Herein, rapid fabrication of glass MLA using laser-assisted contactless hot embossing process is proposed.CO2 laser irra...
