LASER DIODE TESTING
Jul 2001Keithley Instruments Inc.Request Info
Keithley Instruments Inc.'s model 2520 is a light intensity-current-voltage test system for the electrical characterization of laser diodes in the chip or bar state or in finished modules. The company says the single-instrument system can test laser diodes in pulse mode up to 5-A peaks. Besides its pulsed current output, the device has three measurement channels, one of which measures voltage across the laser diode. Source and measurement algorithms are contained within the unit, which is operated with a user-supplied PC controller, an optical spectrum analyzer and a wavelength meter.
