Researchers have developed a spiral-shaped lens that maintains clear focus at different distances in varying light conditions. The new lens works much like progressive lenses used for vision correction but without the distortions ...
For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive, compact, and stable laser sources that ...
As a structure composed of two-dimensional arrays of microscale lenses, micro-lens array (MLA) has attracted the attention of both academia and industry due to its distinctive optical properties and wide applications. Recently, ...
Researchers have developed a way to create freeform optical components by shaping a volume of curable liquid polymer. The new method is poised to enable faster prototyping of customized optical components for a variety of ...
Researchers at Brussels Photonics, Vrije Universiteit Brussel, have developed a 'first time right' design method that eliminates the "step-and-repeat" and "trial-and-error" approach in optical system design. They demonstrated ...
"Image" is everything in the $20 billion market for AR/VR glasses. Consumers are looking for glasses that are compact and easy to wear, delivering high-quality imagery with socially acceptable optics that don't look like ...
A trio of physicists from the National Autonomous University of Mexico and Tec de Monterrey has solved a 2,000-year-old optical problem—the Wasserman-Wolf problem. In their paper published in the journal Applied Optics, ...
Camera performance on mobile devices has proven to be one of the features that most end-users aim for. The importance of optical image quality improvement, and the trend to have thinner and thinner smartphones have pushed ...
Most of us know optical lenses as curved, transparent pieces of plastic or glass, designed to focus light for microscopes, spectacles, cameras, and more. For the most part, a lens' curved shape has not changed much since ...
Lenses and mirrors with freeform surfaces enable designers to focus light within optical devices that are lighter, more compact, and more effective than ever before.
