AR glass (Anti-Reflective Glass) is a type of glass that has multiple coatings applied to its surface to reduce reflection and increase light transmission. This glass provides better visual performance under various lighting conditions by reducing reflected light and enhancing display clarity and contrast.
Cleaning
The finished glass cover needs to undergo thorough cleaning before coating to remove dust, grease, and other impurities. This step usually employs ultrasonic cleaning methods.
Coating
This is the core step in AR glass production. Through vacuum coating technology, multiple layers of anti-reflective coatings are deposited on the glass surface. The coating materials usually include silicon dioxide (SiO2), titanium dioxide (TiO2), etc. These materials have different refractive indices, and by precisely controlling the thickness and order of the coatings, reflection reduction is achieved.
Curing
After coating, the layers need to be cured to enhance adhesion and durability. Curing is usually done in a high-temperature furnace, with the temperature and time adjusted according to the coating materials and thickness.
Inspection
After curing, the AR glass undergoes comprehensive quality inspection, including light transmission, reflection, coating uniformity, and other indicators, to ensure each piece meets design requirements.
Packaging
The finished AR glass is cleaned and dried, then packaged in a dust-proof manner to ensure it remains uncontaminated and undamaged during transportation and storage.
Medical Devices: Provides clearer display effects, helping medical personnel read information under various lighting conditions.
Smart Home: Used in smart mirrors, smart appliance displays, etc., offering a better visual experience.
Industrial Control: Ensures the visibility and operability of control panels and screens in strong light environments.
Automotive Displays: Improves the readability of dashboards and navigation screens, reducing visual interference while driving.
AR glass, through the addition of multiple anti-reflective coatings on its surface, effectively reduces reflected light and increases light transmission. It is widely used in medical devices, smart home products, industrial control systems, and automotive displays. The manufacturing process includes cleaning, coating, curing, inspection, and packaging, ensuring the product has excellent optical performance and durability.
