Custom1mm 1.5mm 2mm 2.5mm 80mm optical half ball lens bk7 k9 Glass sapphire lens optical design
The K9 Spherical Ball Lens is a precision-engineered optical component designed for efficient light focusing, collimation, and coupling in compact optical systems. Manufactured from high-quality K9 optical glass (a material similar to BK7 but optimized for cost-effective optical applications), the K9 Spherical Ball Lens offers excellent transparency in the visible spectrum, stable refractive properties, and good mechanical durability. Its highly symmetrical spherical geometry enables uniform light propagation and reduced optical distortion when properly aligned within optical assemblies.
In practical optical system design, the K9 Spherical Ball Lens is widely used in fiber coupling, laser diode integration, and miniature optical modules where space efficiency and optical performance must be balanced. Due to its smooth surface quality and consistent refractive index, the K9 Spherical Ball Lens ensures reliable beam shaping and improved light transmission efficiency. It is particularly suitable for industrial and commercial optical applications where cost efficiency, stable performance, and ease of integration are essential requirements.
