Detection Equipment Sapphire Optical Windows High Pressure Resistant;

Monocrystalline Al2O3 sapphire all surface polished sapphire crylinder rod lens sapphire plunger stick

Sapphire is a single crystal form of Al2O3 with good chemical, mechanical and optical properties. Sapphire is resistant to strong acids and can be used in corrosive environments. The surface is scratch and abrasion resistant with a Knoop hardness of up to 1800 parallel to the optical axis (C-axis) and a Knoop hardness of 2200 perpendicular to the optical axis.

Uncoated sapphire windows are suitable for harsh conditions, including high temperature, high pressure, high vacuum or corrosive environments. Sapphire has high compressive strength and is resistant to strong acid corrosion.

• Sapphire is Ideal for high temperature, high pressure or strong vacuum environments and have corrosion resistant
• Transparency from 170 nm to 5.5 µm
• Very hard and more durable than standard optical glass;
• Unique properties of sapphire material
• High temperature and high pressure treatment

Sapphire windows are highly resistant to extreme temperature and pressure changes. These windows are often used as viewing windows to observe the interior of vacuum chambers or chambers containing high temperature plasma.

Wide transmission range

Uncoated sapphire is transparent over a broad wavelength range from 170 nm to 5.5 μm.

Notes on Birefringence

SAW series sapphire windows have random axis orientation. Since sapphire is slightly birefringent, this can cause a slight change in the polarization state of the transmitted light.
