Double Convex Lens for Automotive Lighting | Foshan Geqin

Our double convex lenses for automotive applications feature precisely matched convex surfaces on both sides for superior optical performance. These lenses utilize optical-grade materials (PC or PMMA) with exceptional clarity (90%+ light transmission) and minimal chromatic aberration. The symmetrical convex design provides shorter focal lengths and greater light-bending power than single convex lenses of equivalent thickness. We manufacture lenses with various curvature combinations (typically R1:R2 ratios from 1:1 to 1:3) to achieve specific optical characteristics. The production process maintains tight tolerances on center thickness (±0.05mm) and surface profiles (within 0.025mm) for consistent focusing performance. Our double convex lenses demonstrate excellent resistance to thermal stresses and environmental factors. We offer various diameter options (20-200mm) with precise edge thickness control for different lighting applications. The lenses incorporate specialized mounting features for secure alignment in optical assemblies. Our quality control includes comprehensive testing of focal properties and light transmission characteristics. The double convex design minimizes spherical aberration compared to single convex alternatives. We can customize solutions with aspheric surface profiles for advanced optical correction. All lenses meet relevant automotive standards for performance and durability in lighting systems.
