Sapphire Viewports
UV and DUV Sapphire Windows/Viewports |
Sapphire viewports are available with view diameters up to 3 inches, and are bakeable to 450˚C. Single crystal, sapphire windows, with either 0˚ or 90˚ orientation, offer excellent transmission from 250 nm to 4 microns. |
UV Sapphire Specifications
Leak Rate: | <2x10(-10) atm cc/sec He |
Parallelism: | <3 Arc Minutes |
Flange Material: | 304/316 Stn. Stl. |
Surface Finish: | 50/20 |
Thermal Range: | -100°C to 450°C |
Material: | Sapphire |
UV Transmission: | 50% @ 250nm (external) |
