Tunable microlens arrays using polymer network liquid crystal
Abbreviated Journal Title
liquid crystals; microlens; tunable focal length; Optics
A tunable-focus microlens array based on polymer network liquid crystal (PNLC) is demonstrated. The PNLC was prepared using an ultraviolet (UV) light exposure through a patterned photomask. The photocurable monomer in each of the UV exposed spot forms an inhomogeneous centro-symmetrical polymer network which acts as a lens when a homogeneous electric field is applied to the cell. The focal length of the microlens arrays is tunable with the applied voltage. (C) 2003 Elsevier B.V. All rights reserved.
