Achieve an efficient configuration targeting communication LDs! LD chips can be stored in a gripping state, allowing for high-speed automatic measurement.
This device is an LD test system that automatically measures and sorts the electrical and optical characteristics of long-wavelength (optical communication) laser diode bare chips at high speed. <Features> ■ LD chips adhered to a blue sheet are supplied and automatically transported at high speed from gripping ring state to measurement and classification. ■ Measurement items (front/back LIV, λ characteristics) can be measured as standard items under two temperature environments. ■ Measurement sorting can be performed at any temperature from -40°C to +95°C. ■ Simultaneous IL measurement of FRONT light and BACK light is possible. ■ The SH gauging method is adopted for chip positioning. ■ The use of a focusing lens system has eliminated the alignment time for wavelength measurement. ■ Up to 13 cameras monitor the presence and condition of LD chips at each position, making it easy to understand operating conditions and adjust various parts. *For more details, please download the PDF or feel free to contact us.

Company information
Alphax developed its first laser diode tester in 1981 and has since provided numerous inspection facilities alongside the evolution of laser diodes. Laser diodes continue to evolve year by year as key devices that realize cutting-edge technology, and there are currently three major markets. The first is the optical communication market. The year 2019 marks a turning point with the full-scale introduction of a new communication network known as 5G (fifth-generation mobile communication). The 5G network is rapidly spreading as infrastructure supporting IoT and autonomous driving. The second is the lighting and display market. Various applications using blue lasers (such as headlights, HUDs, HMDs, laser TVs, etc.) have been invented, and this field is expected to expand rapidly in the future. The third is the VCSEL laser market for infrared distance sensors. This includes areas such as smartphones using facial recognition, security gates, and autonomous driving sensors that detect surrounding obstacles. We will continue to provide inspection facilities that support the production of various laser diodes, based on our extensive track record and know-how.
