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.
