The invisible light spectrum, encompassing ultraviolet and infrared wavelengths, has long beguiled the human eye. A revolutionary lens technology is now making this unseen light accessible, heralding ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...

Scientists have unraveled the evolutionary journey of a unique type of photosynthesis that allows some bacteria to harness far-red light, a region beyond the visible spectrum. This discovery could ...

Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized ...

The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...

A spectrometer is a pretty common lab instrument, useful for determining the absorbance of a sample across a spectrum of light. The standard design is simple; a prism or diffraction grating to break ...
