LED remains the dominant sapphire application. Sapphire substrates are ideal for use in LED applications due to high-temperature resistance, high strength, good electrical insulation, and low dielectric loss. Sapphire substrate in LED lighting helps prevent stray currents caused by radiation from spreading to nearby circuit elements. Its crystal structure also allows LED lights to have a wider beam angle

CRYSCORE OPTOELECTRONIC LIMITED has been a professional manufacturer specialized in high-quality sapphire wafers and optical windows since 2008. With over 12 years of experience, CRYSCORE can provide 1-inch to 8-inch standard or custom sapphire wafers with any orientation and any thickness applied to epitaxy, as well as sapphire windows with any specifications applied to optics. Patterned sapphire substrates and sapphire ingots also can be provided.

As the sapphire substrate is still a key building block for LEDs, general lighting is expected to continue providing solid demand for substrate material from the LED industry in the following years
