Hyper Hemisphere Sapphire Dome |
| |
The Hyper Hemisphere Sapphire Dome is specifically designed for defense applications, offering a wide viewing angle that is crucial for such uses. This dome can be custom fabricated with a diameter of up to 300mm, surface finish of 40/20, surface roughness of 10 Angstroms, and a surface figure of 1.0 fringe over any 50mm diameter on both faces. |
| |
When anti-reflective (AR) coated on both sides, the Hyper Hemisphere Sapphire Dome provides up to 99% transmission from UV to IR. Additionally, precise edge steps and end profiles can be custom fabricated to accommodate special mounting surfaces, ensuring compatibility with a variety of defense-related applications. |
