Custom Borosilicate Glass Aspheric LED Lens for Enhancing LED
Efficiency Material Composition
The lens is precision-engineered from borosilicate glass, a high-performance material known for its low thermal expansion,
chemical durability, and optical clarity. Customized with an aspheric (non-spherical) surface design, it is manufactured using advanced molding or diamond-turning
techniques to achieve ultra-precise curvature. Key Properties Thermal Stability: Withstands extreme temperatures (-50°C to 450°C), preventing
deformation under prolonged LED heat exposure. High Refractive Index: Optimizes light transmission (up to 99% in visible spectrum) and
minimizes Fresnel losses. Low Dispersion: Reduces chromatic aberration, ensuring consistent color fidelity. Chemical Resistance: Resists corrosion from moisture, UV radiation, and harsh
environments.
Functional Benefits Enhanced Light Collimation: The aspheric shape eliminates spherical aberration, focusing LED
light into a uniform, narrow beam with minimal scatter. Improved Efficiency: Reduces energy loss by 15–20%, boosting lumen output and lowering
power consumption. Precision Beam Control: Custom curvature enables tailored beam angles (e.g., spotlights,
floodlights) for targeted illumination. Longevity: Maintains optical performance over time, unlike plastic lenses
prone to yellowing.
Applications Automotive Lighting: Headlights, fog lights, and interior LEDs requiring heat
resistance and precise beam patterns. Industrial Lighting: High-bay LEDs, UV curing systems, and machine vision where
thermal stability is critical. Architectural Lighting: Facade and accent lighting with customizable beam spreads. Medical Devices: Surgical and diagnostic equipment needing distortion-free,
high-intensity light. Consumer Electronics: Projectors, flashlights, and smart home lighting.
