Double-Convex Lens
Changchun Yutai Optics Co., Ltd., based in Jilin Province, China, manufactures double‑convex lenses with diameters ranging from 5 mm to 500 mm. The lenses can be supplied in BK7, fused silica, germanium, silicon or calcium fluoride, each finished to a surface figure of λ/2. Diameter tolerance is held at +0.01 mm / -0.01 mm, thickness tolerance at ±0.1 mm, and paraxial focal length tolerance within ±2 percent, while centration is guaranteed at 90 percent.
In the optics industry, BK7 is a common crown glass with a refractive index of about 1.517 at the sodium D‑line, and fused silica is valued for its low thermal expansion. Surface quality of 60‑40 scratch‑and‑dig or better aligns with the standard for precision imaging components. Protective bevels of 0.25 mm at 45° are routinely applied to ease handling, and customers may request anti‑reflection or broadband coatings, which are applied according to their own specifications.
These lenses are typically used in imaging systems, laser collimation assemblies, microscopy objectives and scientific instrumentation, making them attractive to OEMs, research laboratories and system integrators. Buyers should confirm minimum order quantities, packaging details and incoterms directly with the supplier, as these terms are not listed in the public data. Payment conditions and lead times are also subject to negotiation on a case‑by‑case basis.

Sourcing Double-Convex Lens from Changchun Yutai Optics Co., Ltd. - China Import Guide
Before placing an order, verify the exact material grade, surface figure and coating specifications required for your system. Request a sample drawing or CAD file to confirm that the lens dimensions and tolerances meet your design. It is also advisable to ask for a material test report, especially when using germanium or calcium fluoride, to ensure optical performance.
Discuss logistics early: confirm the preferred Incoterm (e.g., FOB, CIF), the expected lead time for the chosen material and coating, and the payment terms that suit both parties. Because the supplier’s response rate is currently zero, arrange a direct email or phone contact to secure clear agreement on shipping dates and freight responsibilities.
Plan for quality assurance by arranging a third‑party inspection before dispatch, and request the relevant certificates such as ISO 9001 or material test certificates. Insist on a final acceptance test that measures diameter, surface figure and coating performance against the agreed tolerances. Proper documentation will smooth customs clearance and protect your downstream production.
