The Bosch laser level proved to be a serious piece of machinery during testing. It is highly accurate, with a maximum deviation of just 3/32 of an inch at 30 feet. The three 360-degree planes were ...

Having a laser onsite is a nice touch, but having a rotary axis is almost unheard of. These nifty add-ons enable your laser to cut and engrave radially symmetric parts. Their pricetags usually ...

Most laser measures have an accuracy of one-sixteenth of an inch. Lower-quality measures may have accuracies to one-eighth of ...

Earlier this year the U.S. Army shot down a number of hostile drones in the Middle East using a weapon long dismissed as more science fiction than reality—the laser. After decades of costly ...

You can fall back on price or reputation, probably both, and Bosch power tools enjoy a reputation ... for working (especially ...

The other one I’d like to single out is I think the most recent acquisition, a Bosch cordless model he bought several years ago. It’s similar in size and capabilities to the Makita save for ...

For many years, semiconductor lasers, tiny chips emitting light, have been the workhorse of the optical communications industry, sending data signals around the world via a web of optical fibres.

NASA’s Psyche spacecraft is depicted receiving a laser signal from the Deep Space Optical Communications uplink ground station at JPL’s Table Mountain Facility in this artist’s concept.

One solution could come from a technology called “free-space optics” (FSO), which uses lasers to transfer data through the air. It was pioneered in the 1960s by NASA and for decades has been a ...

Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors ...
