Candles create a warm light ideal for an unforgettable dinner or a relaxing evening at home. However, other illumination options, such as electric candles, emit harmful blue wavelengths that disrupt the circadian cycle.
Researchers at the University of Central Florida are working on new photonic materials that could someday aid in the development of low-power, ultra-fast light-based computing.
Researchers have employed liquid crystals for the first time to develop a flat magic window, which is a transparent device that generates a concealed picture when light shines on it. The technology offers a fresh take on an age-old light trick.
Artificial intelligence, self-driving vehicles, drones, and metaverse technologies are gaining traction as core sectors of the future, and demand for computers that can swiftly calculate and analyze enormous volumes of data is skyrocketing.
The emergence of a new scientific field called nonlinear optics was accompanied by the first demonstration of the laser in 1960.
MKS Instruments, Inc., a global provider of technologies that enable advanced processes and improve productivity, has announced the Ophir® SupIR 60-1200 MWIR f/4 lens, the latest addition to the company's series of lenses designed for SXGA/HD 10 µm and 15 µm VGA pitch FPA (focal plane array) cooled MWIR cameras.
Low-cost, strong photoluminescence quantum yield, and excellent color purity define metal halide perovskites. Perovskite light-emitting diodes have made rapid progress in recent years, with intriguing applications in lighting and display.
While scanning cathedral stained-glass windows, scientists from the Nara Institute of Science and Technology developed a novel method to compensate for fluctuations in illumination. This technique might be extended to other culturally significant objects to help frame their colors in the most authentic way possible.
Scientists from Umeå University and Uppsala University have formulated a new technique to regulate the light emission of light-emitting electrochemical cells (LECs). details of the study have been published in Advanced Materials.
A rare spectroscopy technique performed at Swinburne University of Technology directly quantifies the energy required to bind two excitons together, providing for the first time a direct measurement of the biexciton binding energy in WS2.
