Powerful Full Automatic Electro-Optical Characterization For Laser Bars
Description of the OptoSystem Laser Diode Bar Tester VMSB3000
Tight specification requirements are a trademark of laser diodes and a close monitoring of key parameters is required to timely recognize dangerous trends in production and to sort out unfit diodes before shipping or mounting into their packages. This full automatic tool from Opto System is a masterpiece in integration of machine vision, testing equipment and laser bar handling know-how. The tool automatically picks up the laser bar from your tape or GelPak, places it on the temperature-controlled chuck and performs a full electro-optical characterization of all emitters on each bar. This includes the integral light output power as well as its angular far-field distribution, the spectrum, the electrical properties and optionally the backside emission too. According to the specified criteria, the laser bars are sorted in different GelPaks or Rings. Optional customization includes multiple chucks for multiple temperature testing for instance.
