Editor’s Note
This article outlines a strategic technology partnership between Japan’s ExtenD and Silicon Valley’s Diamond Quanta, focusing on diamond optics. The collaboration aims to advance product development in this specialized field.

ExtenD Co., Ltd. (Headquarters: Tosu City, Saga Prefecture; President: Mitsuru Kitai) has signed a Memorandum of Understanding (MOU) with Diamond Quanta, Inc., based in Mountain View, California, USA, regarding a strategic technology partnership in the field of diamond optical products.
Through this partnership, ExtenD will participate as a strategic technology partner in Diamond Quanta’s diamond optical product line. The companies will build a co-creation technology platform by leveraging ExtenD’s “uniform diamond film formation technology from nano to polycrystalline” based on its proprietary large-scale Hot Filament CVD (HFCVD) technology.
Furthermore, through collaboration with Heller Industries, Inc. (Headquarters: New Jersey, USA), Diamond Quanta’s system ODM/integrator, a seamless supply chain from R&D to mass production will be established. This will strengthen the manufacturing system for optical applications and pave the way for global mass production.

This strategic partnership is expected to lead to the commercialization of diamond optical products in diverse fields such as photonics, precision optics, and consumer devices by fusing state-of-the-art diamond film formation technology, optical design technology, and system integration technology.
