The identification method of Sapphire Windows is as follow: Laboratory testing. There are related instruments in the laboratory for jewelry identification. Generally speaking, the commonly used identification instrument is a refractometer. Sapphire windows is man-made, but its refractive index is almost the same as natural, around 1.76~1.77. It also has a heavy refractive index like crystal, which is 0.008. The refractometer can detect the refractive index of the gem surface.

Zoolied Inc. offers in a variety of Sapphire Optics , such as Optical Sapphire rings, Step Glass, Sapphire Rod Lens and sapphire tubes. Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR).

Sapphire is a single crystal form of Al2O3, with a favorable combination of chemical, mechanical and optical properties. Sapphire is resistant to attack by strong acids, enabling use in a corrosive atmosphere. It is resistant to scratch and abrasion with very high Knoop hardness of 1800 parallel to the optic axis (C-axis), 2200 perpendicular to the optic axis.
Sapphire's hardness allows it to be made into much thinner optics than other substrates. Sapphire is chemically inert and insoluble to water, common acids, and alkalis for temperatures up to 1,000 °C. Sapphire is transparent in the UV to the IR (150?nm - 4.5μm). It is commonly used in IR laser systems and has an ordinary refractive index of 1.754 and an extraordinary refractive index of 1.747 at 1.064 μm.
