Optical Substrates & Precision Glass Assemblies

Founded in 1955, FUJITOK is a full-service supplier of precision glasses, substrates and custom optical parts and components. FUJITOK offers the best selection of optical-grade glasses and substrates, from plano to curved substrates in a variety of shapes.

In addition to flat substrates, FUJITOK also offers 3-D glass works such as cells, tubes, prisms and wedges with/without coating.

From Sample Works to Volume Production

Our strength lies in having two experienced fabrication workshops specialized in optical grade precision cutting and polishing, From sample works for prototyping to commercial volume production, we deliver custom optical parts and components exactly to your requirements at reasonable cost.
The accuracy of our polishing work is controlled based on the following checking criteria:

Surface Form: Flatness/TWF 1/20 waves @632.8nm per 25.4mm (1inch) circle
Parallelism: ≦ 5 arc sec.
Surface Roughness: Ra ≦ 0.3nm

Markets We Serve

We serve a broad range of industrial and R&D markets in global scale such as optoelectronics, telecommunication, laser optics, analytical instruments and medical equipment. Our customerbase includes Philips, Hitachi, Canon, Nikon, Shimazu, Sony, to name a few.
