Polished Sapphire tube for optical spectroscopy measurements |
| |
Synthetic sapphire posses unique combination of excellent optical, physical and chemical properties. Due to its high hardness, high strength, high temperature resistance, purity, chemical durability and excellent transmission bandwidths, sapphire tube can withstands harsh chemicals such as fluorine plasma, acid and alkaline, while allowing for safe observation and spectral analysis of fluids and gasses. |
| |
The edge-defined-film fed method (EFG) provides the ability to produce various sizes of sapphire tubes with minimal or no grinding. |
| |
With more than 20s year diverse experience in the growth, processing and production of sapphire tubes, our capabilities ensure consistent high quality and excellent transmission. |

| Key properties |
| 1. High transparent to wavelengths of light between 0.3 μm (UV) and 5 μm (IR), Polished sapphire tubes are used in various analytical instruments applications that transmit ultraviolet, visible and infrared ligh. |
| 2. Extremely hard and scratch resistance, Sapphire tube is virtually scratch-proof which helps it maintain its integrity in harsh environments. |
| 3. High melting temperature (2030°C), excellent thermal conductivity and heat resistance, Sapphire tube is ideal material for high-temperature applications. |
| 4. Exceptional chemical stability and corrosion resistance, The chemically inert property enables sapphire tube to withstand aggressive chemicals. |
| 6. Outstanding electro-insulation properties |
| 7. High operating pressures |
