カドミ光学工業 List of Products and Services

Our company utilizes advanced glass polishing and machining processes to manufacture a variety of glass products. We can process high-purity quartz glass, which has high transparency and stability, with high precision, allowing us to produce components with excellent dimensional accuracy and optical properties. We have also achieved optical contact (a strong bond without the use of adhesives), enabling the production of parts with shapes and precision that were previously thought to be difficult to achieve with glass products. By creating tools with minimal fluctuations due to temperature changes, we can leverage the transparency of glass for visualization, contributing to improved accuracy and efficiency in visual inspections. In particular, products with optical contact do not use adhesives, eliminating absorption and scattering caused by adhesive layers, and there is no shrinkage or thermal expansion, allowing us to produce high-precision and high-quality components. While it may seem that machining holes, grooves, and screw holes in glass materials, which are hard and brittle, is difficult, there are many cases where it can be addressed with clever engineering. Please feel free to contact us.
