2520INT Integrating Sphere for Pulsed Measurements The Model 2520INT Integrating Sphere is designed to optimize the Model 2520 Pulsed Laser Diode Test System's optical power measurement capabilities . It allows the testing of devices with pulse widths as short as 500ns . The short pulses of the Model 2520 combined with the speed of the Model 2520INT make them ideal for measuring the optical power of laser diodes at the bar or chip level, before these devices are integrated into temperature-controlled modules . When connected to the Model 2520 via a Simplifies pulsed measurements of optical power low noise triax cable, the Model 2520INT allows the Model 2520 to make direct, high accuracy measurements of a laser diode's optical power . The results are expressed in milliwatts . Designed specifically for Pulsed laser Diode Testing Keithley developed the Model 2520INT to address the challenges specific to pulse testing laser diodes, which include short pulse periods and fast rise times . For example, when testing laser diodes in pulse mode, the opti- cal head used must provide a response that's fast enough to measure light
