High Precision Borosilicate Glass Aspheric Lens for Indoor LED Lighting
1. Material Composition:
Optical-Grade Borosilicate Glass: High-purity material (e.g., Schott B270) with low thermal expansion (3.3 × 10⁻⁶/K) and exceptional homogeneity.
Aspheric Surface Design: Precisely polished non-spherical curvature to eliminate spherical aberration and reduce lens count in optical assemblies.
2. Key Properties:
High Light Transmission: >92% visible light transmission with minimal scatter and distortion.
Thermal Stability: Withstands LED operating temperatures (up to 150°C) without deformation or performance loss.
Precision Tolerance: Surface accuracy < λ/4 @ 632.8nm and roughness < 5Å for sharp focus control.
Chemical Resistance: Immune to humidity, household chemicals, and UV degradation.
3. Core Functions:
Beam Shaping: Converts raw LED output into uniform, glare-free illumination with precise field angles (e.g., 15°-120°).
Aberration Correction: Aspheric design eliminates spherical and comatic distortions for edge-to-edge clarity.
Efficiency Optimization: Maximizes lumen output by reducing optical losses compared to traditional spherical lenses.
4. Applications:
Commercial LED Lighting: Downlights, track lights, and panel lights for offices, retail spaces, and museums.
Architectural Lighting: Precision accent lighting, wall washers, and decorative luminaires.
Smart Lighting Systems: Lenses for tunable-white and human-centric lighting applications.
High-End Residential:
Recessed lighting and premium pendant fixtures requiring precise
light control.
