1. Feature of our Optical synthetic Sapphire crystal

OEM Size and Design, any shape is ok;
Widely used for optical window, lens, military, etc; The material is synthetic sapphire(hardness 9H)
High Crystal Purity:> 99.995%;

Crystal orientation: Provide A plane, R plane, C plane, M plane and other random planes for sapphire crystal product.

Directional accuracy: ±0.05°We can always provide high-quality service, we will respond to the customer's requirements in a short time.

In addition to optical sapphire glass, we can also make other materials of the optical window, sapphire wafer.

We specialize in the following synthetic sapphire crystal products:
Precision Optics — Micro & Macro Sapphire Windows, Wafers & Flat Products, Tubes, Rods, Spheres & Special Shapes.Our synthetic sapphire growth methods are chosen according to the appropriate application.
Sapphire plasma tubes for semiconductors
Sapphire scanner windows
Sapphire display windows
LED Semiconductors


2. Advancement On sapphire Crystal compare with other glass

1) High temperature resistant, Sapphire Round / Rectangular Optical Window can work

under 1200°C continuously, and in short time can even work under 1450°C,
its softening temperature is 1650°C, and the melting temperature is 1750-1800°C.
2) Corrosion-resistant, Except hydrofluoric acid, Quartz Plate Of Optical Grade
do not react with any acid and base except hydrofluoric acid. the stability is
30 times of the ceramic, and 150 times of stainless steel.
3) Excellent thermal shock stability
4) High transmission to 85%
5) Electric insulation, it is 10000 times of usual glass
