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.
