Ejection Characteristics and Drop Modulation of Acoustic Inkjet Printing Using Fresnel Lens
Journal of Fluid Science and Technology, 2009 Acoustic Inkjet Printing uses an acoustic beam focused on a free liquid surface for drop ejection. This method can eject small drops without precise nozzle fabrication in comparison with thermal inkjet and piezoelectric inkjet.

The use of convex lens as primary concentrator for multi-junction solar cells
Emergent Scientist, 2018 A concentrator lens system was designed for a multi-junction solar cell, CDO-100-C3MJ, with an added feature − a convex lens was added above the Fresnel lens in order to improve the output power of the setup and reduce the need for the use of solar ...

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres
Advanced Functional Materials, EarlyView.MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...

Tight focal spots using azimuthally polarised light from a Fresnel cone [PDF]
, 2020 When focusing a light beam at high numerical aperture, the resulting electric field profile in the focal plane depends on the transverse polarisation profile, as interference between different parts of the beam needs to be taken into account.
