A few weeks ago, we took a look at the KIWI P1 Indiegogo campaign. Promising to be “a highly accurate, fast and easy-to-use laser measurement tool,” the company sent us one for review. Our KIWI P1 ...

Scientists from the University of Rochester and UC Santa Barbara have built a laser so small it can sit on a penny. But don’t let its size fool you. This tiny laser could power the next generation of ...

Laser power measurement and force metrology are interlinked disciplines dedicated to quantifying the interaction between light and matter. In contemporary research, these fields have evolved from ...

An innovative arrangement employing diverse electronic and optical principles and components leads to precision frequency ...

Engineers often have to measure power, and this power can take many forms: DC or low-frequency, wired or wireless RF, or optical. In addition, the dynamic range of power to be measured spans many ...

Engineers know that measuring dc or low-frequency electrical power is fairly straightforward, but such measurements become more difficult as you go up the spectrum into the tens-of-gigahertz range.

Ophir Photonics Group, global leader in precision laser measurement equipment and a Newport Corporation company, today announced four new thermal laser sensors designed for measuring high pulse ...

The Z500 laser measurement sensor combines a wide-beam laser (4 to 45mm in width) and a two-dimensional CCD to conduct highly accurate two-dimensional measurements in a single procedure. This ...

[Andrew] got a little help from his friends to hack a laser distance meter. Using laser distance meters as sensors is one of the great quests of hackers – with good reason. Accurate distance readings ...

Sometimes you absolutely, positively need to know the angle of the cutting edge on a knife. When you do, the best tool for the job is a laser goniometer, and [Felix Immler] shows us three different ...
