When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

Laser diodes, the devices that illuminate telecom fiber-optic cables, require light-current-voltage (L-I-V) measurements during production. These measurements let you characterize a laser diode's ...

The ubiquitous diode—though you likely have a good understanding of this device, this primer of sorts acts as a quick-read guide, highlighting many of the essentials you need to know. The diode is a ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

A multimeter is a helpful tool for advanced electrical projects. But multimeter symbols and their meanings can be cryptic to ...

ILX Lightwave, a Newport Corporation brand, introduces the LRS-9580 Calibration System. The new system is a complete, self-contained transportable unit capable of calibrating fixtures, shelves, and ...

If you’ve played around with laser diodes that you’ve scavenged from old equipment, you know that it can be a hit-or-miss proposition. (And if you haven’t, what are you waiting for?) Besides the real ...

FitTech, a provider of LED probing, testing, and sorting equipment, has expanded its footprint in new industries such as compound semiconductor and laser diode testing, where it anticipates ...

Laser diodes are critical components powering innovations across industries, from telecommunications and medical devices to autonomous vehicles and consumer electronics. As demand for high-performance ...

Four New Jersey cities have begun testing new street lamps powered by light-emitting diodes. The new LED lamps are expected to reduce energy consumption significantly, have a longer life expectancy ...

How a Virginia Tech research team constructed its novel thermal diode. Test results of the thermal diode. Electrical engineers are obviously very familiar and comfortable with the basic diode, a ...
