Before coating, we perform precision polishing on optical glass, glass wafers, and glass substrates to significantly enhance the adhesion between the coating layer and the glass surface or lacquer. This polishing process not only improves the durability and stability of the coating layer but also ensures optimal optical surface quality of the final product. We offer both single-side and double-side polishing options, allowing flexible adjustment of smoothness and specifications based on different application needs. Through high-precision processing, we can control glass materials to extremely high standards, including:

• TTV
• IRR
• PV

Optimizing these critical parameters enables our optical glass, glass wafers, and glass substrates to deliver exceptional performance in advanced semiconductor applications such as Advanced Packaging, MicroLED displays, and MEMS device manufacturing—providing customers with reliable, high-quality solutions.
