USHIO OPTO SEMICONDUCTORS, INC. (UOS), formerly Hitachi/Opnext and Epitex,  provides optical devices for use mainly in the IT industry, such as laser diodes and light-emitting diodes, utilizing unique laser technologies and manufacturing expertise, since its establishment.

On July 1, 2016, USHIO OPTO SEMICONDUCTORS, INC. merged the LED business of USHIO EPITEX INC. By consolidating the semiconductor laser business, we will be able to increase the business efficiency and respond to an increasingly diverse business environment swiftly and effectively to accelerate the growth of the OPTO Semiconductor business.

Change the world with USHIO light sources—

We will continue to seek and pursue all possibilities in Light sources for the OPTO Semiconductors to provide optimized optical solutions for our customers.

Your continued support is greatly appreciated.
