Q5: What coating options are available?

A: Felix Glass provides a full portfolio of functional thin-film coatings for optical glass and display cover glass, including AR anti-reflection coating, AG anti-glare coating, AF anti-fingerprint coating and high-reflection silver coating for solar mirrors. We also support custom coating development for special optical spectrum requirements.

AR (Anti-Reflection Coating): Reduce surface reflection and boost light transmittance. Mainly applied for automotive and industrial display glass, optical windows. We can tune AR coating for visible, near-infrared or UV wavelength bands to match your optical system requirement. It greatly improves sunlight readability for touch display panels.

AG (Anti-Glare Coating): Diffuse reflected light to eliminate sharp mirror-like glare. AG treatment scatters ambient reflection, so users will not see clear environmental reflection on screen surface. It is popular for industrial HMI and automotive touch displays to protect eyesight and improve touch operation experience.

AF (Anti-Fingerprint Coating): Oleophobic and hydrophobic nano coating on glass top surface. It repels oil, water and fingerprint residues. Fingerprint marks can be wiped away easily, keeping glass surface clean for touch screen operations. AF coating is usually combined with AR or AG coating as top layer.

High-reflective silver coating: This coating system is designed for solar CSP mirror glass. It achieves ≥95% high reflectivity across solar spectrum, equipped with copper barrier layer and multi-layer protective waterproof coating to resist outdoor weathering and corrosion for long service life in solar power plants.

Except these standard coating types, our thin-film team can also develop customized coating stacks for special projects, such as IR cut coating, band pass coating or low-reflection coating for specific wavelength requirements. All coatings go through strict adhesion test, abrasion test and aging reliability test before delivery. We will recommend the most suitable coating combination after learning your application environment and optical targets.
