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 ...

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 ...

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 ...

(Nanowerk News) 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 ...

Astronomers using the HARPS planet-hunting machine at ESO's La Silla Observatory in Chile have made the first-ever direct detection of the spectrum of visible light reflected off an exoplanet. These ...

Integrated photonics is a rapidly-evolving industry sector, with infrared spectrum applications including high-speed 5G networks, biosensors on chip, and driverless cars. Researchers are now exploring ...
