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 Model 2520 Pulsed Laser Diode Test System performs electrical characterization of laser diodes in either the chip/bar state or in finished products. According to its manufacturer, the 2520 is the ...

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 ...

When checking and verifying capacitors, inductors, diodes, bipolar transistors, and cables, the gamut of test methods can range from those used to confirm a defective component to identifying the ...

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 ...

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 ...

A working group of the international PV Quality Assurance Task Force has been undertaking research and testing initiatives aimed at improving the design and long-term reliability of module junction ...

LIVERMORE, Calif., Dec. 17, 2019 (GLOBE NEWSWIRE) -- To provide a proven test solution for probing millimeter wave (mmW) and terahertz (THz) semiconductor devices above 500 GHz, FormFactor, Inc.

A team of laser scientists in Germany say that their optical frequency reference setup has successfully completed a test run on a sounding rocket. Potentially, the achievement paves the way to a ...

With the ongoing increase in module operating current, a reliable junction box is critical for modules which are to last for 25 to 30 years. This article will analyse which factors need to be ...
