Optics is possibly the oldest scientific discipline and basic ideas of reflection and refraction were already mentioned in a treatise by Ptolemy in the second century AD 1. Light has been harnessed ...

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 ...

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 ...
