Fresnel lenses are designed so their light can be pointed in just one direction, meaning drivers in a lane may see only the ...

Try on an Oculus Rift or HTC Vive and one of the first things you’ll probably notice looking through the lenses are fine concentric circles, creating something many call ‘God Rays’—especially ...

Anti-Reflection (AR) coatings represent a key innovation in optics. AR coatings are central to the proper manipulation of light, mitigating Fresnel reflection, enhancing system throughput and ...

We learned last week that PSVR 2 will use Fresnel lenses, which have a range of advantages over traditional lenses, but also come with a big downside: god rays. However, Sony may have a trick up its ...

Micro-machining could be used to create almost flat, Fresnel lenses, that boost the electrical efficiency of solar panels, according to new research. Micro-machining could be used to create almost ...

Fresnel zone plates (FZPs) are widely used for X-ray focusing and imaging thanks to their compactness and high resolution compared to refractive or mirror-based X-ray optics. However, achieving high ...

Apple's AR headset or "Apple Glass" device may use a movable display to compensate for motion blur, while fresnel lenses could help keep the weight of the headset down for users. Apple is long-rumored ...

Light-emitting diodes (LEDs) have been applied in general and many other lighting settings for decades due to their superior energy efficiency, longer lifetime and relatively small bulk compared to ...
