K9 Spherical Ball Lens

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.

Ball lens

Spherical Ball Lenses are commonly used for laser Collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling.Larger spheres are easier to handle and ease the sensitivity of translational alignment. However, smaller spheres has the benefit of fitting into smaller packages.Ball lenses are highly polished spheres made of optically transparent homogeneous materials.Carefully controlled manufacturing process produces spheres with precise diameters and unsurpassed Surface quaWe supply optical spherical ball lens,Half-ball (hemispherical) lenses are ideal for applications such as fiber communication, endoscopy, micros copy, optical pick-up devices, and laser measurement systems.
