Lasers are known for the monochromatic nature of their light, so much so that you might never have thought there could be such a thing as a white laser. But in the weird world of physics ...

The receiver module has a phototransistor to pick up the infrared laser light, and an LM386 audio amplifier to generate the audio signal sent to a pair of headphone. The need to be well-aligned ...

A team of materials scientists, medical researchers and engineers affiliated with a large number of institutions across ...

The Attosecond Science group at the Center for Free-Electron Laser Science has developed a novel light source capable of ...

Unlike traditional bubble levels, laser levels project a beam of light that serves as a reference point for various construction and DIY tasks. Whether you’re hanging pictures or tackling larger ...

Holiday light projectors can cast everything from snowflakes and snowmen to laser light shows with a kaleidoscope of colors, so it’s easy to find a model that matches your aesthetic. Still ...

Light is now used for everything from laser eye surgery to telephone technology. The potential military applications of light are straight out of science fiction, and within a decade light may be ...

Though primarily known for cameras and office equipment, Ricoh boasts that its lenses are the preferred choice of top ...

The light’s ability to penetrate the skin was shown to help promote collagen and tissue growth. It’s also used in photodynamic therapy, which utilizes low-power red laser light to drive a cell ...

Lasers are devices that produce intense beams of monochromatic, coherent radiation. The original term "laser" (dating to about 1960) was an acronym for "light amplification by stimulated emission of ...

Here’s how it works. The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That's about 186,282 miles per second — a universal constant ...
