ST-LDC systems are fully configurable all-in-one laser diode and LED characterization devices for industries and RD laboratories. They are designed to measure and analyze all major characteristics of laser diodes and LEDs.
ST-LDC systems are fully configurable, all-in-one laser diode and LED characterization devices for industries and R&D laboratories. They’re designed to measure and analyze all major characteristics of laser diodes and LEDs in a fast and reproducible way. They’re ideal tool for data sheet generation, quality control, failure analysis and research activities with semiconductor emitters.
ST-LDC systems are customizable tool to meet various needs required by different activities. They can measure devices from UV-LEDs to telecom laser diodes and high power laser bars, we can features a camera assisted pick’nplace robot capable of collecting diodes from customer supplied trays and finally marking and sorting them after the tests.
ST-LDC systems are having modular construction based on robust field bus technology. This construction makes high scalability and easy maintenance possible while keeping number of components minimum. On
ST-LDC system without pick’nplace robotics, devices under test (DUTs) are loaded into the system on multichannelload-traysthat are equipped with an inpidual low resistance bypass switch over each DUT to allow series connected devices operating even in case of open circuit or empty slots. Load tray also features channel specific temperature and voltage monitors and optionally a channel specific temperature control. ST-LDC capabilities
