Optical Grade Borosilicate Glass Prismatic Lens for Specialty Lighting

Optical Grade Borosilicate Glass Prismatic Lens for Specialty Lighting

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.

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).

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.

Architectural Lighting:
- Cove lighting diffusers
