Sapphire Optical Dome Windows
Precision sapphire dome optics for subsea, aerospace, defense and harsh environment imaging systems.
Sapphire optical dome windows are used where high strength, scratch resistance and long-term optical durability are critical.
Sapphire combines excellent optical transmission with exceptional hardness, making it ideal for subsea cameras, aerospace sensors and harsh environment imaging systems.
Compared with standard optical glass materials, sapphire offers significantly improved abrasion resistance and mechanical durability, particularly in demanding marine and industrial environments where long service life is important.
Sapphire dome windows are commonly used in hemispherical and hyperhemispherical geometries for applications requiring wide-angle imaging, pressure resistance and environmental protection while maintaining optical clarity.
Custom sapphire dome windows can be manufactured to customer drawings with a range of diameters, wall thicknesses, edge configurations and optional anti-reflective or protective coatings depending on application requirements.
