Introduction

Final inspection is to check various functional indicators of the products that are about to leave the factory, and is a necessary link in the actual production process. This station allows students to use a semiconductor laser tester to measure the power, threshold current, operating voltage and other parameters of the prepared semiconductor laser, generate a data report, and evaluate the reliability of the device.
