Colloidal photonic glasses offer an appealing way to produce vivid colors without any chemical dyes—but so far, a stubborn ...

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 ...

Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image. That's why high-power microscopes are so big and telephoto lenses so long.

Astronomers using the HARPS planet-hunting machine at the European Southern Observatory’s (ESO) La Silla Observatory in Chile have made the first-ever direct detection of the spectrum of visible light ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

Jan. 21 (UPI) --Scientists have discovered a molecule that can take advantage of the entire visible spectrum of sunlight. The molecule can both efficiently absorb sunlight and operate as a catalyst, ...

Is there really treasure at the end of the rainbow? Yes, say scientists who have fired ultrashort laser pulses into a novel fiber that transforms one color into many. The remarkable spectrum exiting ...
