A research team led by SUTD has created nanoscale glass structures with near-perfect reflectance, overturning long-held ...

An international team of researchers including Kavli IPMU has for the first time observed a new class of exotic atomic ...

This work describes the hydrogenation, writing and thermal treatment process of seed fiber Bragg gratings - FBG, written with spectra in the visible range by an Ion argon laser. Those gratings have ...

PRINCETON, N.J. — SightLogix has announced dual-spectrum AI for its dual-sensor SightSensor product series. This new capability integrates thermal and visible AI validation that provides intrusion ...

To understand where black falls on the color spectrum, first consider what light actually is. Light is radiation visible to the human eye Light is energy called electromagnetic radiation.

The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can't see, has an even lower frequency ...

This infrared image from the James Webb Space Telescope, released by NASA on Aug. 31, 2023, shows internal details of the evolving supernova 1987a that have never been observed in the visible spectrum ...

For the first time, researchers in Europe have witnessed Mars’ green night sky in the visible light spectrum, further confirming a decades-old suspicion about the Red Planet’s eerie atmosphere.

Hong et al. constructed an unprecedented bright, smooth, and flat 300-5000 nm ultraviolet-visible-infrared full-spectrum femtosecond white-light laser source by exploiting the efficient second ...

Researchers in Quebec, Canda, have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright ...
