Light Lens Lab has introduced the 50mm f/1.5 "Z21" optic, which pays homage to one of the most revered and rare cine lenses in photography history: the P Angenieux Type S21 50mm f/1.5. Just ...

Researchers have demonstrated the first planar lens that works with high efficiency within the visible spectrum of light -- covering the whole range of colors from red to blue. The lens can ...

The material forms to the shape of the light, allowing us to create a 3-D structure. You cannot accomplish a gradient index with traditional manufacturing processes.” The lens could make terahertz ...

A technique developed by Princeton engineers allows the easy creation of nano-scale patterns on uneven surfaces and without the normal requirements of a vibration and oxygen-free environment.

The performance was remarkable: The lens increased the intensity of the output light by more than 30 times at the focal point. And it did this across a broad range of wavelengths, from the near ...
