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.

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 ...

Following its recent launch of integrating sphere laser power detector series, Gentec-EO now adds another model of fast laser power detectors, the IS50A-1KW-RSI. Probably the most remarkable feature ...

Accurately measuring the power in a laser beam is a difficult proposition. There are nearly as many different kinds of meters as there are lasers, and none of them are cheap. If you tried to use a ...

The new laser power detector HP60A-15KW-GD-QBH is ideal for those in need to measure average laser power for burn-in tests, during long periods of time or even quickly in the field with the simplicity ...

Designed to replace the legacy FieldMate and FieldMaxII platforms, the new meters feature a modern 5-inch color touchscreen, ...

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 ...

PRIMES has released the ScanFieldMonitor 2D (SFM 2D), developed to meet the requirements of laser-scanner applications in ...

Always on the lookout for better ways to measure all kinds of things, researchers have published a detailed study suggesting an "elegant" improved definition for the standard unit of light power, the ...

In ancient times when someone needed to make a measurement, they would turn to something close at hand, often literally a hand. A tradition that originated thousands of years ago in Egypt that is ...
