Achieve an efficient configuration targeting communication LDs.
This device is an LD test system that automatically measures and sorts the electrical and optical characteristics of long-wavelength (optical communication) laser diodes in bare chip state at high speed. <Features> ■ LD chips affixed to a blue sheet can be supplied and stored in a gripping ring state. High-speed fully automated transport from supply to measurement and classification. ■ Measurement items (front/back LIV, λ characteristics) can be measured as standard items under one temperature environment. ■ Measurement and sorting can be performed at any temperature from -40°C to +95°C. ■ Simultaneous measurement of FRONT light and BACK light IL is possible. ■ The SH gauging method is adopted for chip positioning. ■ The use of a focusing lens method has eliminated the alignment time for wavelength measurement. ■ Up to 9 cameras monitor the presence and condition of LD chips at each position. This allows for easy understanding of operating conditions and adjustments of various parts.

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.
