High Precision K9 Rod Lens

K9 optical rod lenses are high-performance cylindrical glass lenses made from optical-grade K9 (equivalent to BK7) material. With excellent light transmission and low optical distortion, these lenses are ideal for laser beam shaping, fiber optic coupling, endoscopic imaging, and LED collimation. K9 rod lenses are widely used in medical devices, laser systems, industrial sensors, and scientific instruments. Available in custom diameters and lengths, with optional AR coating to reduce reflection and enhance performance. Our precision-polished rod lenses feature high surface quality and tight tolerances, making them suitable for demanding optical applications. OEM/ODM support and global shipping available.
