    Optical Grade Borosilicate Glass Prismatic Lens for Specialty Lighting



    Optical Grade Borosilicate Glass Prismatic Lens for Specialty Lighting


    1. Material

    • Core Substrate: Optical-grade borosilicate glass (e.g., Schott Borofloat® 33, Corning 7980) with exceptional purity (>99.9% SiO₂).

    • Key Additives: Boron trioxide for low thermal expansion, alkali oxides for chemical resistance.

    • Coatings: Optional AR/IR coatings for wavelength-specific transmission enhancement.


    2. Key Properties

    • Optical Clarity: >92% transmission (400–700nm VIS range), minimal bubbles/inclusions (Class 0-1 per ISO 12123).

    • Thermal Resilience: Low CTE (3.25 × 10⁻⁶/K), withstands thermal shocks up to 160°C ΔT.

    • Surface Precision: λ/4 surface flatness, 80-50 scratch-dig standard.

    • Refractive Control: Precise refractive index (nd=1.47–1.51) for controlled light bending.

    • Durability: Resists acids, water, and UV degradation (unlike acrylic).


    3. Primary Function

    • Light Redirection: Uses prismatic geometry to refract, reflect, or disperse light via total internal reflection (TIR).

    • Beam Shaping: Converts raw light into uniform patterns (e.g., flat-top, linear, or asymmetric distributions).

    • Glare Reduction: Minimizes hotspots by diffusing light angles.

    • Color Fidelity: Maintains CRI >95 with minimal chromatic shift.


    4. Critical Applications

    • Architectural Lighting:

      • Cove lighting diffusers

      • Linear LED channel systems

      • Museum accent fixtures

    • Entertainment:

      • Stage/studio spotlight lenses

      • Projection system homogenizers

    • Commercial/Industrial:

      • Retail display case lighting

      • Machine vision inspection optics

      • Medical device illuminators (endoscopes, surgical lights)

    • Transportation:

      • Aircraft cabin mood lighting

      • Automotive signal lenses
