Import Bi-Concave Lenses — Buy in Bulk from Supplier in China

Bi-concave lenses from Jilin Tianhua Opto Electrical Technology Development Co., Ltd. are precision optical elements engineered to diverge collimated light beams. These lenses feature symmetrical concave surfaces on both sides, producing a negative focal length that spreads light outward. The supplier’s lenses are manufactured from optical glass, with anti-reflective coatings applied to minimise glare and maximise transmission efficiency for applications demanding low reflection.

The lenses are available in multiple diameters and thicknesses, allowing customisation for project-specific requirements. Optical glass is the standard material for such components, offering clarity and minimal distortion. Surface quality typically meets scratch-dig specifications of 40-20 or better, with standard tolerances for centration and thickness variation. Bi-concave lenses are commonly used in beam expansion, light projection systems, and as part of Galilean telescopes where divergence is required.

Industries utilising these lenses include medical diagnostics, scientific instrumentation, and laser optics. Buyers typically source these for integration into imaging systems, microscopes, and custom optical assemblies. The lenses are shipped from Changchun, Jilin Province, with trade terms such as FOB or CIF available. Verification of exact diameters, thickness ranges, and coating specifications is recommended, as these can vary by batch. Lead times and packaging details should be confirmed directly with the supplier.
