Sapphire Windows Glass Crystal Flat Sapphire Optical Glass Window AR Coating

Properties of Optical Sapphire Window:
Optical Windows are used as viewports to protect other components within an optical assembly, instrument, or laser. In certain applications, optical windows are required to withstand harsh environmental conditions and provide high levels of performance and reliability. Sapphire window has several unique properties that make it the ideal material for these applications.
1. Synthetic Sapphire, the single crystal form of Al2O3, is one of the hardest materials ( 9 Mohs hardness). Because of its
structural strength, the sapphire window can be made much thinner than other common optical windows, with better transmitance performance.
2. High thermal stability and excellent thermal conductivity make the sapphire window suitable for the applications in high power. The loss in a sapphire window is less than in another common optical window.
3. Sapphire windows can withstand considerably higher temperatures than most optical windows with zero degradation.
4. Sapphire Windows will not get dark and lose their brilliancy when exposed to UV light.
5. Sapphire windows are extremely stable and resistant to attack by strong acid due to sapphire’s high dielectric constant.
6. Sapphire windows offer wideband transmission from UV to Mid-IR (0.15-5.5µm).
All these unique properties make sapphire windows the ideal material for extreme mechanical, chemical & optical application

Applications:
Optical Windows are flat, plane-parallel, transparent optical surfaces designed to protect sensors and other electronicinstruments from environment conditions.
Optical Window selection considerations include material transmission properties as well as scattering, strength and resistance to certain environments. Their use should not impact on magnification of a system. Optical Windows can be optically polished and incorporate an element for diffusing light source to control illumination.
AR coatings can be applied to ensure maximum transmission performance for a particular wavelength. The windows are made in a range of materials including UV Fused Silica, Quartz, IR Crystals and optical glasses. Our optical window properties include x-ray protection, non-browning to UV light and light transmission from deep ultra violet to far infrared.
Optical Windows products include wedges, substrates, discs, flats, plates, rods, protection windows, laser windows, camera windows, light guides and domes.
Our Windows are used by scientific and industrial companies across the world of medical, defence, instrumentation, laser, research and imaging.
All our Optical Windows can be supplied from a standard range stock. We also supply custom optical windows made to your specification, sizes and specific design.
