Fresnel Phase Plates as Reconfigurable Microfluidic Lenses

Abstract

In this study, Fresnel phase plates were tested as reconfigurable lenses. The lenses were constructed from a Fresnel pattern which was transferred to a silicon substrate via photolithography. A layer of PDMS was spin-coated on the substrate and cured to produce the lens. This lens was attached to a PDMS control layer which enabled specific regions of the… (More)
