Sankyo Optical Industry Corporation (Sankyo)
Since 1929, Sankyo Optical Industry Corporation (“Sankyo”) have produced a variety of camera lenses and industrial lenses. Sankyo is the No.1 SME in Japan for spherical lens manufacturing. We specialize in Arduous Custom Optics manufacturing. Arduous means small quantities, difficult-to-cut materials and high precision.
Sankyo has broad experience in optics manufacturing with special expertise in:
- Geometries: spheres, aspheres, large optics(>300mm), micro-optics(<5mm)
- Materials: glasses, ceramics, crystals, metals
- Wavelengths: UV, Visible, NIR, IR
Our optics are adapted for Aerospace, Laser Processing, Lithography Machine and Factory Automation. Sankyo is certified to ISO 9001:2015 and ISO 14001:2015.
Sankyo’s strength is precise attention to detail. Highly skilled “TAKUMI” integrate the diverse customized equipment and state-of-the-art equipment to develop cutting-edge polishing technologies. “Prototype products” and “Single item” orders of various designs in small quantities are also accepted. We have diversified experience as optical lens processing partners for R&D department.
We own more than 30 types of domestic Transmission Elements (“TEs”) with a shape accuracy of PV better than lambda/20, a total of more than 90 lenses. These highly accurate TEs and ASI(Q) are combined to process high-precision lenses. If our requested TEs cannot measure the requested spherical lens, we will design and manufacture in-house, new TE’s that meet your requirements.
