LD 960-32 life test system for semiconductor laser diodes uses the company's conductive thermal control technology as opposed to an air-based oven for precise control of diode temperature during the life test process. The system can perform life tests on up to 960 diodes with 30 diodes at 32 independent thermal sites, and each individual diode is driven by a microprocessor-controlled source.
