Optical Ball Lenses are manufactured from optical materials such as BK7 glass, fused silica, CaF2, or infrared crystals. Their spherical geometry enables uniform refraction and high coupling efficiency between optical fibers and light sources. Production requires high-precision grinding and polishing to achieve tight dimensional tolerance, low surface roughness, and optical homogeneity. These lenses are widely used in fiber communication systems, laser modules, barcode scanners, and sensing devices.
