Founded in 1955, Fujitok Corporation is a premier Japanese designer, manufacturer, and global distributor of precision custom glass substrates, optical lenses, and complex electro-optical assemblies. With over seven decades of specialized expertise, the company operates via a robust internal framework including two subsidiary workshops and a vast network of dedicated industrial partners. This integrated supply chain allows Fujitok to excel in advanced single-point diamond turning, precise microfabrication, and state-of-the-art flat and curved polishing technologies. The company delivers ultra-high-fidelity components fabricated from a diverse selection of premium optical glasses, fused silica, color filter glass, and high-purity infrared (IR) crystals—such as Sapphire, Calcium Fluoride, Germanium, Silicon, and Zinc Selenide. In addition to traditional flat substrates and wafers, Fujitok produces intricate 3D glass works including optical cells, tubes, wedges, and prisms, which can be delivered with or without specialized anti-reflective or reflective custom coatings. Serving highly demanding international sectors—such as medical instrumentation, aerospace engineering, defense imaging, and semiconductor inspection—their products are integral components inside advanced microscopes, astronomical apparatus, broadcasting equipment, and digital machine vision cameras. By balancing cutting-edge engineering with highly flexible logistics, Fujitok provides full-service scalability, seamless engineering support, and rapid turnaround times for everything from custom low-volume R&D prototypes to large-scale commercial OEM mass production.
