Aplanatic lens can correct both spherical and coma aberrations. In this report, an aplanatic doublet with acrylic plano-concave lens as a cover and room temperature vulcanizing (RTV) silicon-rubber ...
In this experimental study two solar technologies concentration and the flat plate collector were combined in one solar air heater with a Linear Fresnel Reflector (SAHLFR). A rectangular useful duct ...
By leveraging ZHIYUN’s advanced multi-layer optical technology, the Mini Lens Reflector, the company claims, corrects the uneven beam and harsh transitions typically found in traditional Fresnel ...
Profoto has unveiled the Fresnel Small, a modern take on the classic Fresnel light designed to offer photographers precise control over their light beams. Thanks to its high-quality lens and robust ...
By combining chemistry and nanotechnology, her group has developed a low-cost and scalable method to print ultra-thin lenses using a material called lithium niobate. A new way to control light ...
Ultra-Thin Lenses That Generate New Light Using this technique, the ETH researchers in Grange’s group succeeded in creating the first lithium niobate metalenses with precisely engineered ...
