The Model 228 lens from Resolve Optics has become an industry standard for Reflected Ultraviolet Imaging Systems (RUVIS) used to detect fingerprints or bloodstains undiscovered during an initial crime ...

Lenses are the most widely used optical devices. Camera lens or objectives, for example, produce a sharp photo or video by directing light at a focal point. The speed of evolution made in the field of ...

In recent years, the world of optics has undergone a major shift. New research shows how light can be bent, focused, and even changed in color using structures so small they’re invisible to the eye.

Illinois researchers developed a spherical lens that allows light coming into the lens from any direction to be focused into a very small spot on the surface of the lens exactly opposite the input ...

Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength of incident light. The study is published in Advanced Materials. Lenses ...

Infrared light passes through the metal lens and is converted into violet light and focussed in a focal point due to the material and the special surface structures – enlarged in the magnifying glass.
