Sapphire Screen Protector description:

Sapphire Crystal is very popular among wristwatches, Because of its amazing features:

Sapphire Bezel Insert are manufactured from single crystal sapphire, extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis.making them ideal for demanding applications (such as laser systems).Because of its hardness (second only to Diamond), Sapphires are used in industrial applications such as components for watch crystals and movement bearings, scientific instruments, high-durability windows, and insulating substrates in special purpose solid state electronics

• Very wide optical transmission band from UV to near-infrared, (0.15–5.5 µm)
• Significantly stronger than other optical materials or standard glass windows

• Thinner and Stronger than Standard Glass Windows

• Most sapphire glass found in wristwatches is actually synthetic (man-made) sapphire, rather than the naturally occurring material you may be familiar with. As with acrylic, this isn’t technically ‘glass’, rather, transparent crystallised Aluminium Oxide; usually produced in a laboratory. You will struggle to scratch a sapphire crystal with anything other than a piece of diamond.

  Synthetic Optical Sapphire has no colouration and with a selection of grades of Sapphire available, transmission ranges from 170nm to 6 microns.
