Sapphire Rods Light Cone Rods Sapphire Discharge Needles Specialized for Semiconductor Equipment
Sapphire light cones are specialized optical components manufactured from high-purity single-crystal aluminum oxide (Al₂O₃ purity ≥99.99%). As a professional optical components manufacturer, ZMSH maintains complete production lines for crystal growth, precision machining, and coating deposition. The products are fabricated using advanced EFG (Edge-defined Film-fed Growth) technology, exhibiting exceptional axial optical uniformity and radial refractive index consistency. The unique tapered design enables efficient beam coupling, expansion, or focusing functions, making it a critical component in advanced optical systems.
