High-Transmittance Convex Lenses for Automotive Lighting | Foshan Geqin

Our high-transmittance convex lenses for automotive lamps deliver exceptional light transmission performance (92%+ for PMMA, 90%+ for PC) across the visible spectrum. These optical components utilize premium-grade optical plastics with minimal impurities to maximize light throughput. The lenses incorporate specialized anti-reflective coatings that reduce surface losses to less than 1% per surface. We manufacture lenses with precisely controlled center thickness (±0.05mm) to maintain optimal optical path lengths. The high-transmittance design minimizes light absorption within the lens material (<2% for 5mm thickness). Our production process includes stringent controls on material selection and processing parameters to ensure consistent transmittance values. We offer various UV-filtering options that protect against solar degradation without significantly reducing visible light transmission. The lenses demonstrate excellent resistance to environmental factors that could affect transmittance, including temperature extremes and chemical exposure. Our quality control includes spectrophotometric analysis to verify transmittance at multiple wavelength points (400-700nm). The high-transmittance lenses maintain performance through years of service without significant degradation. We can customize solutions to meet specific spectral transmission requirements for different lamp applications.
