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 ...

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 ...

Keithley Instruments, Inc. has introduced a dual-channel picoammeter with dual ±30V independent, non-floating bias sources and 1fA measurement resolution. The Model 6482 picoammeter provides two ...

The fruit of a collaboration with Labsphere, the 2500INT is a custom-designed integrating sphere optical head that facilitates direct optical measurement of laser diode output power when used with ...

Paul Crump, head of the High-Power Diode Laser Lab at the Ferdinand-Braun-Institut (FBH) in Berlin, will lead the newly formed working group together with Will Fenwick from LLNL. Along with the FBH, ...

SUMMARY: On April 9, 2012, the U.S. Department of Energy (DOE) published a notice of proposed rulemaking (NOPR) in which DOE proposed a test procedure for light-emitting diode (LED) lamps (hereafter ...
