Sapphire Step glass cover
 Sapphire optical stepped glass windows are used in a wide variety of applications where spectral isolation is required. They are widely used in electro-optics, aerospace, bio-medical areas. We can custom made according to customer's requirements. The two round surfaces of the stepped windows will be polished. other surfaces only fine grinding.
