Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor ...

Scientists have used a new lens to focus all the colors of the rainbow into one point. This is the first time a single lens has been used to focus the entire spectrum of light, including white light.

First used as status and indicator lamps, and more recently in under-shelf illumination, accent lighting, and directional marking applications, high-brightness LEDs have emerged within the last six ...

US scientists have discovered that using wavelength-selective, semi-transparent PV modules to absorb the blue light spectrum while transmitting red light onto crops can increase crop yield. “Today’s ...

The photosynthetic pigments of phototrophic microorganisms cover different regions of the solar light spectrum. Utilization of the light spectrum can be interpreted in terms of classical niche theory, ...

Our little-known ability to see infrared light could occur when pairs of photons combine their energies to appear as one "visible" photon Although we do not have X-ray vision like Superman, we have ...
