Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical ...

As a structure composed of two-dimensional arrays of microscale lenses, micro-lens array (MLA) has attracted attentions of both the academia and industry, due to its distinctive optical properties and ...

The function and use of micro-lenses mainly include focusing, imaging, and optical function enhancement in specific applications. Micro-lenses are small optical components that can accurately control ...

LASER COMPONENTS offers micro lens arrays from partners Holo/Or for laser beam homogenising and shaping. Micro lens arrays consist of micron-scale plano-convex refractive lenses packed together on a ...

Researchers detail how they used a type of 3D printing known as two-photon lithography to create lenses that combine refractive and diffractive surfaces. In a new study, researchers have shown that 3D ...

Machine-learned, light-field camera reads facial expressions from high-contrast illumination invariant 3D facial images. A joint research team led by Professors Ki-Hun Jeong and Doheon Lee from the ...
