Durable Borosilicate Glass LED Aspheric Lenses for High-Intensity Curing Applications
Material: Made from borosilicate glass (SiO₂ + B₂O₃ + alkali metals), a robust material inherently resistant to thermal shock, chemical corrosion, and mechanical stress. Optional coatings enhance UV/IR resistance for extreme environments.
Properties:
Thermal Durability: Withstands rapid temperature changes (up to 500°C) without cracking, ideal for high-power LED heat.
Optical Precision: Aspheric design eliminates spherical aberration, ensuring sharp focus and uniform light distribution.
Mechanical Strength: High hardness (Mohs 7.5) resists scratches and wear, extending lifespan in harsh industrial settings.
Chemical Inertness: Unaffected by solvents, resins, or moisture, maintaining clarity in corrosive environments.
Function: Converts high-intensity LED light into tightly collimated beams for ultra-fast curing of photosensitive materials. Minimizes energy loss while maximizing irradiance (W/cm²) for efficient polymerization.
Applications:
Industrial: UV curing of adhesives, inks, and coatings in electronics (PCB assembly) and automotive (headlight sealants).
Medical: Dental curing lamps and sterilization equipment requiring precision and durability.
Additive Manufacturing: High-resolution 3D printing and rapid prototyping with consistent light output.
Optoelectronics: Encapsulation and lensing for high-power LED arrays in lighting systems.
