Detailed
Automotive ADAS Optical Components
77GHz Millimeter Wave Radar Protective Cover Glass | AR+AF Coated Radar Dustproof Optical Window
Felix Glass produces customized millimeter wave radar dustproof protective optical glass, also known as radar protective cover glass. As standardized core automotive safety parts for passenger fuel and new energy vehicles, our radar windows perfectly match front and rear 77GHz anti-collision millimeter wave radar modules. This ADAS radar dustproof window serves as collision avoidance radar cover for automotive active safety systems, with steady recurring bulk orders from global automotive Tier 1 suppliers and vehicle OEMs.
Engineering pain points we resolve
Common Challenges For Automotive Radar Cover Procurement
Unqualified coating causes high electromagnetic attenuation and unstable radar signal output
Coating peeling after temperature cycling, unable to meet long-term vehicle durability standards
Direct engineering overview
Advantages of Felix Glass ADAS Radar Protective Glass
We adopt high-strength chemically strengthened aluminosilicate automotive radar tempered glass as substrate, reaching Mohs 7 hardness to achieve excellent scratch and impact resistance. It withstands gravel impact, sand abrasion, long-term UV radiation and rain corrosion during highway and off-road driving, avoiding permanent surface damage that weakens radar detection stability.
Mohs 7 Hardened Substrate
Chemically strengthened aluminosilicate glass against stone impact and surface abrasion.
Low-Loss AR+AF Coating
Minimize millimeter-wave attenuation while repelling mud, snow, rain and road contaminants.
Wide Temperature Stability
Reliable optical performance from -40℃ to 85℃ with durable coating after thermal cycles.
