Al2o3 Crystal Materials Step Sapphire Optical Windows With High Thermal Conductivity - China

price: check with company for price

Sapphire step window, sapphire optical lens, Al2O3 single crystal glass, sapphire optical glass step sapphire plate sapphire optical windows, Sapphire window introduce Single crystal sapphire possesses a unique combination of excellent optical, physical and chemical properties.

The hardest of the oxide crystals, sapphire retains its high strength at high temperatures, has good thermal properties and excellent transparency.

It is chemically resistant to common acids and alkali at temperatures up to 1000 C as well as to HF below 300 C .

These properties encourage its wide use in hostile environments where optical transmission in the range from the vacuum ultraviolet to the near infrared is required.

Sapphire is anisotropic hexagonal crystal.

Its properties depend on crystallographic direction (relative to the optical C-axis).

Features: Transmission in 0.3-5.0m, no absorption in 2-3m Extremely hard and durable High thermal conductivity High bulk damage threshold - - - - Materials characteristics compare | - - - - - - - - Item | B270 | CaF2 | Ge | MgF2 | N-BK7 | Sapphire | Si | UV Fused Sillca | ZnSe | ZnS | Refractive index(nd) | 1.523 | 1.434 | 1.003 | 1.413 | 1.517 | 1.768 | 3.422 | 1.458 | 2.403 | 2.631 | Coeffcient of dispersion(Vd) | 58.5 | 95.1 | N/A | 106.2 | 64.2 | 72.2 | N/A | 67.7 | N/A | N/A | Density(g/cm3) | 2.55 | 3.18 | 5.33 | 3.18 | 2.46 | 3.97 | 2.33 | 2.20 | 5.27 | 5.27 | TCE(m/m) | 8.2 | 18.85 | 6.1 | 13.7 | 7.1 | 5.3 | 2.55 | 0.55 | 7.1 | 7.6 | Soften Temperature() | 533 | 800 | 936 | 1255 | 557 | 2000 | 1500 | 1000 | 250 | 1525 | Knoop hardness(kg/mm2) | 542 | 158.3 | 780 | 415 | 610 | 2200 | 1150 | 500 | 120 | 120 | - - - - CommenSpecifications: - - - - Material: | Sapphire | Dimension Tolerance: | +0.0, -0.1mm | Thickness Tolerance: | 0.1mm | Surface quality: | 80/50 | Clear Aperture: | >85% | Flatness: | per 25mm | Parallelism: | 3' | Bevel: | <0.25mm X 45 | Coating: | Upon requirement | - - - - grade: Sapphire optical Orientation: C <0001>1, size: 57x50mm, width: 35x29mm, 0.03mm, Thickness: 5mm0.02mm SD: 60/40, Company Introduce SHANGHAI FAMOUS TRADE CO., LTD. locates in the city of Shanghai, Which is the best city of China, and our factory is founded in Wuxi city in 2014 - We specialize in processing a varity of materials into wafersand customized lens, substrates and custiomized optical glass parts.
