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 ...

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 ...

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 ...

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 ...

The Keithley System 25, a fully customizable test system for the light-current-voltage (LIV) characterization of laser diodes and assembled laser-diode modules (LDMs), lets users choose only 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 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 ...

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 ...
