UV Grade Sapphire Windows |
| UV grade sapphire, the highest-grade, is the purest form, completely free of insertions, micro-bubbles, scattering, and block boundaries. |
| UV grade sapphire features a lower rate of lattice distortion, less light scattering and resistant to solarization. These characteristics make it an excellent choice for windows that need to withstand high-intensity light and extreme temperatures. |
| With its ability to withstand high temperatures that would otherwise melt or distort other materials, UV sapphire window can be exposed for years without any loss of properties. That's why UV sapphire windows are frequently used in IR analytical equipment, lasers, and instruments where long-term reliability at harsh conditions is required. |
| UltiTech custom fabricates precision UV Sapphire Windows ideal for use in imaging and laser applications, especially those in harsh environments requiring tough, durable protective windows. |
| Precision UV Sapphire Windows |
| • Feature UV sapphire substrates with improved surface quality specifications 20-10 scratch-dig to minimize scatter in UV applications, compared to standard surface finish of 60-40 scratch-dig. |
| • Provide high transmission from 170 – 5000nm and, due to sapphire’s structural strength, feature thinner thicknesses than standard glass windows, minimizing absorption. |
| • Extreme hardness second only to diamond, high thermal conductivity, and resistance to common chemical acids and alkalis. |
| • Feature UV sapphire window with high precision surface flatness λ/5 @ 633nm, these windows are designed to improve image quality and minimize birefringence effects. |
