About Sapphire
Sapphire Optical Window is a type of window made from sapphire crystal.
Sapphire is a natural gemstone known for its outstanding hardness, strength, and superior optical properties.
It is commonly used as a protective window for sensors, capable of withstanding higher pressure and stronger vibrations.
It possesses characteristics such as high strength, high hardness, high-temperature stability, and corrosion resistance. Additionally, it can resist corrosion from various chemicals. Due to its excellent optical performance, sapphire optical windows can also support more stable optical signal transmission.
Furthermore, sapphire windows exhibit features like a high excitation energy threshold and good thermal shock resistance, making them widely used in high-energy, high-power lasers, ultrafast lasers, and other high-precision research fields.
Besides,
Sapphire belongs to the trigonal crystal system.
The crystal shape is usually cylindrical, short columnar, plate-like, etc.
The geometric body is mostly granular or dense blocks.
Transparent to translucent, glass lustre. Refractive index 1.76-1.77, birefringence 0.008, strong dichroism.
Inhomogeneous body. Sometimes there is a special optical effect - the starlight effect.
Hardness 9, density 3.95-4.1g/cm3. No cleavage, or crack development.
