The product shall be manufactured from high quality optical grade Czochralski grown color sapphire crystals.

They are widely applied in luxury watches and the dimensions could be customized.

Sapphire optical window sheet is suitable for high pressure, high vacuum or high corrosion environment. Sapphire has strong acid resistance, high compressive strength and high melting point. Our sapphire parallel window has the advantages of low deformation, low scattering and high parallelism.

Sapphire has very stable chemical properties and is not corroded by acid and alkali. The hardness of sapphire is very high, with Mohs hardness of 9, second only to the hardest diamond. It has good light transmittance, thermal conductivity, electrical insulation, good mechanical properties, wear resistance and wind erosion resistance. The maximum operating temperature is 1900 ℃.

Because the high-quality artificial sapphire crystal material has good light transmittance in the wave band of 170nm ~ 6000nm, and the infrared transmittance hardly changes with temperature, the optical elements and infrared transparent optical windows made of high-quality artificial sapphire are widely used in military night vision infrared transparent equipment, low-temperature laboratory observation port High precision instruments and meters for navigation, aerospace and aviation have been fully applied.

Buying Guides

Customers need to know:

1. The products are made according to the requirements of customers. Please contact us before placing an order to confirm the detailed production process, quantity, production period, logistics and other relevant information.

2. Customization needs to know:

(1) Customization: please directly provide dimensions (length * width * thickness, and color quantity) (please consult customer service quotation).

(2) Product processing: please send drawings to the owner, such as CDR, AI, CAD and other vector drawings, and inform the thickness, (consult customer service quotation) to give you a quotation. No friends can draw by hand and take photos for us. We need drawings for complex processing.

3. Please confirm the size and drawing carefully before photographing. Once processed, it will not be returned or changed.

4. There is a certain tolerance for processing and material thickness. Buyers who require no difference should be merciful! The tolerance is about 0.3mm. Once photographed, we do not accept any return or exchange due to tolerance!

Chongqing Silian Optoelectronics Science & Technology Co., Ltd was founded by China Silian Instrument Group Co., Ltd for the development of LED industry. After the acquisition of Honeywell Sapphire business, the company has become China’s first enterprise with the world’s top-quality large-sized sapphire production and R&D capabilities. The company has the world’s leading high-power sapphire substrates technology. Taking the excellent oppotunity, the company has developed LED packaging, LED lighting applications and other industries in succession to project extension in LED industrial chain. Based on the core-technology of sapphire substrates, we have created an area of 1000 mu (approximately 66.7 hectares) to develop LED industrial china from basic materials to high end products and become the most completed and largest semiconductor energy-efficient in dustrial base in Western China.
