Import Cylindrical Lens — Buy in Bulk from Supplier in China

Changchun Gold Dragon Optics Co., Ltd. supplies cylindrical lenses that focus light into a line, suitable for precision optical systems. The lenses are offered with focal lengths from +5 mm up to +1000 mm, covering short‑range beam shaping to long‑range collimation. They are manufactured in a cylindrical shape and can be fabricated from a range of optical materials such as flint glass, UV‑fused silica, infrared fused silica, calcium fluoride (CaF2), germanium (Ge), zinc selenide (ZnSe) and silicon (Si). The catalogue states compliance with ISO and CE standards, confirming adherence to recognised quality benchmarks.

In the optics market, cylindrical lenses are commonly supplied with surface quality of 10‑5 or better and anti‑reflective (AR) coatings to minimise Fresnel losses; these are typical industry specifications. Typical diameter options run between 10 mm and 100 mm, allowing designers to match aperture requirements without custom machining. The material selection influences transmission windows: for example, UV‑fused silica transmits below 200 nm, while ZnSe and Ge are transparent in the infrared region. Such material‑specific performance is standard practice for suppliers serving telecommunications, medical imaging and laser manufacturing sectors.

End users include telecom equipment manufacturers, medical device makers and laser processing firms that need reliable line‑focus optics. Suppliers usually ship lenses under FOB or CIF terms, and packaging is provided in moisture‑controlled containers to preserve optical surfaces during transit. Buyers should confirm the exact material, coating type and packaging details with the supplier before placing an order. Trade negotiations can accommodate both small batch and large‑volume requirements, reflecting the flexible MOQ mentioned in the listing.

Changchun Gold Dragon Optics Co., Ltd. is located at No.286 Torch Road, Changchun 130012, Jilin, China. The company is classified as an imported supplier and carries a harbor trust tier, indicating that it has passed basic verification checks on the platform. Its response metrics show a response rate of 0 % and an average response time of 0 hours, suggesting that communication may require proactive follow‑up. The firm lists cylindrical lenses among its product offerings but does not disclose production capacity or detailed corporate history.

The supplier states that its lenses comply with ISO and CE standards, yet no additional certifications such as RoHS or FDA are mentioned in the listing. Buyers can request further documentation directly from the company to confirm material grades or quality management systems. No explicit minimum order quantity is provided, so the exact MOQ should be clarified during negotiation. The profile does not indicate any third‑party audits or export licences, which importers may wish to verify before finalising a contract.
