Company Information
Individual performance is the true source of efficiency
Sumita Optical Glass has built up a solid record of technical achievement since its establishment nearly half a century ago, in 1953. A continued stream of technological breakthroughs in optical glass, fiber optics and functional glass products have kept Sumita Optical Glass's customers, many of the world's leading companies, at the cutting edge.
The results can be seen today in high-tech products from industrial microscopes, fiberscopes, and special engineering glass to cameras, hard disk data storage devices and laser optical disc players and recorders. But this is only the beginning, as Sumita Optical Glass works to develop the next generation of optical glass, fiber optics and functional glass materials that will make possible the products that designers have yet to imagine.
The most important asset in the development of new technologies is not technology itself, but rather the independent outlook and fresh approach that sets Sumita Optical Glass apart from others in the high-tech glass industry.
This is why Sumita Optical Glass continues to be first with significant advancements that translate into high value-added materials that help create uniquely better products in every application. Sumita Optical Glass's mascot Ranger, the free-range rooster, is symbolic of the courageous and independent attitude that made Sumita Optical Glass a leader in its field.
