PMMA Convex Lenses for Automotive Lighting | Precision Optics

Our PMMA convex lenses for automotive lighting combine optical precision with exceptional durability. These lenses utilize optical-grade polymethyl methacrylate with 92%+ light transmission and excellent UV stability. The convex surfaces are precision-molded to achieve exact curvature radii (typically 30-400mm) for controlled light refraction. We manufacture lenses with various configurations including plano-convex, double-convex, and meniscus designs for different lighting functions. The PMMA material formulation includes specialized additives that prevent yellowing under prolonged sun exposure. Our production process maintains tight tolerances on center thickness (±0.05mm) and surface profiles (within 0.025mm) for consistent optical performance. The lenses feature excellent resistance to the thermal cycling stresses of automotive environments (-40°C to 90°C). We offer various surface treatments including abrasion-resistant hard coatings (up to 3H pencil hardness) for exterior applications. Our quality control includes comprehensive photometric testing to verify beam pattern compliance with regulatory standards. The PMMA convex lenses demonstrate superior weathering resistance, maintaining optical clarity through years of service. We can produce lenses with diameters ranging from 20mm to 250mm to suit various lighting assemblies. All lenses meet relevant automotive standards for optical quality and safety performance.
