Description



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
