| HYT Sapphire Optics offers coatings and metallization solution to our sapphire windows. |

| Sapphire Windows AR Coating |
| Anti-reflective coatings on sapphire windows to reduce transmission loss and improve resistance to scratching. |
| 1. Sapphire substrate has a high refractive index, thus usually requires an antireflection (AR) coating on sapphire windows for sufficient transmission in the region of interest. |
| 2. Sapphire windows normally need to work under extreme operating conditions, so hard AR coating is required to withstand harsh environmental conditions and improve resistance to scratching. |
| Sapphire Windows Metal Coating |
| Metalized Sapphire Windows to create Hermetically sealed optics for harsh or vacuum applications. |
| In some applications where sapphire windows needs to be soldered or bonded to metal. |
| Synthetic Sapphire is a single crystal and high purity, so bare sapphire will not attach to braze or solder alloys on its own. An intermediary thin layers of chrome, nickle and gold around the edge of sapphire windows is required. |
| The metalized edge creates a surface that enable sapphire windows to be brazed into a metal housing. Brazing is the use of melted filler metal to bond two unmelted surfaces. It creates strong bonds between surfaces with small clearances, particularly ideal for sapphire window assemblies applications. When properly done, the joint is hermetic. |
| Through
solderable metallization on sapphire windows, HYT Sapphire Optics creates hermetically sealed optics which are ideal for harsh or vacuum applications. |
