Difference between anti-reflective glass (AR) and anti-glare glass(AG)
The core difference between AR glass and AG glass lies in the principle and applicable scenarios:
AR glass reduces reflection and enhances light transmittance through coating, making it suitable for high-definition display; AG glass achieves anti-glare through surface etching and is suitable for strong light environments.
I.Principle and Appearance
AR glass (anti-reflective glass) :
Multiple layers of optical films (such as magnesium fluoride) are coated on the surface of the glass. The principle of light interference is utilized to reduce the reflectivity (<4%) and increase the light transmittance (peak 99%, average >95%), making the surface smooth and transparent.
AG glass (anti-glare glass):
By using chemical etching or spraying to form a micron-level rough structure on the glass surface, light undergoes diffuse reflection, reducing the reflectivity to less than 1%, and the surface presents a matte and frosted texture.
II.Performance characteristics
A.Light transmittance:
AR glass has a higher light transmittance (>95%) and more vivid colors;
AG glass is slightly lower due to surface treatment (approximately reduced by 5-10%).
B.Anti-reflection effect:
AR glass performs better in low light, with clear images;
AG glass has a stronger anti-glare ability under strong light and reduces the interference of ambient light.
C.Durability:
The AR glass film layer has high hardness (>7H) and can withstand high temperatures (>500℃). The surface of AG glass is wear-resistant, but the touch is slightly rough.
III.Applicable scenarios
AR glass:
high-definition display devices (such as 4K TVS,camera lenses),museum display cases,optical instruments, and scenarios that require high light transmittance and low reflection.
AG glass:
outdoor display screens (such as advertising screens, ATM machines), medical equipment, vehicle screens, in strong light environments that require anti-glare and anti-fingerprint properties.
