Import Ball Lens — Buy in Bulk from Supplier in China

Ball lenses from Vy Optics Photoelectric Technology Co., Ltd are precision optical components designed for light collimation, focusing or coupling in compact systems. This supplier’s units are manufactured with a sphericity tolerance of λ/4, ensuring minimal wavefront distortion in laser diodes, sensors and imaging assemblies. Diameters are available across a range of sizes to match specific optical paths, with materials including BK7 and LASFN9 optical glass for broad-spectrum transmission from UV to near-IR.

The lenses are finished with precision polishing to achieve low surface roughness, typically below 1 nm Ra for visible and NIR applications. BK7 offers a refractive index of 1.5168 at 587.6 nm and transmission above 90 percent between 350 nm and 2 µm, while LASFN9 provides higher index contrast for specialized setups. These lenses are supplied as single elements, with anti-reflective coatings applied on request to reduce reflection losses to under 0.25 percent per surface.

Industrial buyers in electronics, telecommunications and medical diagnostics use these ball lenses in endoscopes, barcode scanners and fiber-optic couplers. Packaging is typically in individual foam-lined cases to prevent surface contact, with bulk shipments palletized for export. Confirm MOQ, lead time and Incoterms with the supplier, as these depend on diameter, material and coating requirements.

Vy Optics Photoelectric Technology Co., Ltd is based at No.128 Taibei Street in the Kuancheng Area of Changchun, Jilin Province, China. The company is registered as an imported-tier supplier and holds a harbor trust classification, indicating a baseline level of verification for export readiness. Its address places it within an established industrial zone, supporting logistics for optical component shipments.

The supplier profile does not list a published response rate or average response time, so direct contact is advised for technical clarification. The company specializes in optical glass components, with ball lenses as a core product line.
