Our converging convex lenses for car lighting systems are precision-engineered to optimize light collection and directional control. These optical components utilize carefully calculated convex curvatures to create controlled convergence of light rays from various source configurations. The lenses are available in multiple convergence angles (30°-120°) to suit different lighting applications. We manufacture lenses with focal lengths ranging from 25mm to 500mm, precisely controlled within ±1% tolerance. The converging effect achieves light collection efficiencies exceeding 90% for properly designed optical systems. Our design process includes advanced optical simulations to predict and verify convergence performance before production. The lenses feature durable optical materials (PC or PMMA) that maintain convergence accuracy across automotive temperature ranges. We offer various surface treatment options including anti-reflective coatings to enhance convergence efficiency. The manufacturing process maintains strict control over lens thickness and curvature to ensure consistent convergence characteristics. Our quality control includes comprehensive testing of focal properties and light distribution patterns. The converging lenses demonstrate excellent resistance to environmental factors that could affect optical performance. We can customize solutions for specific convergence requirements in headlights, fog lights, or auxiliary lighting systems.
