The QuasarBrite narrow-beam LEDs produce a tight beam of high-intensity red, green, or blue light from a surface-mount (SMT) package. Compared to traditional SMT LEDs, these narrow beam LEDs reduce ...

An LED and a semiconductor laser (or laser LED) work in essentially the same way, that is, light is emitted as electrons and holes combine, with emission wavelength dependent upon the materials used.

Scientists at the National Institute of Standards and Technology (NIST) have now developed a highly efficient converter that enlarges the diameter of a light beam by 400 times. NIST physicist Vladimir ...

Scientists have now developed a highly efficient device that enlarges the diameter of a light beam by 400 times. Wider light beams have many applications, including boosting the speed and sensitivity ...

Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a noninvasive and ...
