By deploying X-ray goniometers, OSICO assures to control the orientation of crystal axis precisely maintained from first cut through final products. Our skillful technicians are developing specialized fabrication techniques for crystal components to meet the requirement of the highest standards.

After fabrication and inspection, thin film coatings are applied to each transmission surface. With combination of advanced coating machines and many experienced coating engineers as well as the latest thin film coating design techniques, our coating department is able to do a wide range of the best coatings.
