Sapphire windows

Features：

1. High material purity: sapphire crystals grown by the effervescent method (KY) are of higher purity, with a total impurity content of <2ppm and low absorption and high transmission in the UV band;

2. Surface high quality: Finish at least 40/20 or more, roughness <0.2nm, transmittance surface type better than 1/20;

3. Flawless appearance: chipping, missing corners and internal cracks are not allowed, because the existence of these defects will lead to the extension of defects in the process of the user's use, and ultimately lead to product failure and scrap;

Our sapphire windows are divided into bare windows and windows coated based on specific transmittance needs (enhancement coating or cut-off coating).
