Sourcing Convex lens from Changchun Realpoo Photoelectric Co., Ltd. - China Import Guide
Before placing an order, verify the exact material composition, coating type, and dimensional tolerances required for your application. Request a certificate of conformance and a sample lens for testing, especially if the lenses will be used in high-precision systems such as laser optics or microscopy.
Confirm the packaging method for bulk shipments, as standard 210 x 60 x 40 mm boxes may not be sufficient for large quantities. Discuss Incoterms such as FOB or CIF to clarify responsibility for shipping costs, insurance, and customs clearance. Lead times are not specified, so factor in additional time for manufacturing if custom tolerances or coatings are needed.
Inspect the lenses upon arrival for surface defects, centration accuracy, and coating uniformity. Use a surface profilometer to verify lambda/10 flatness and a spectrophotometers to check AR coating performance if applicable. Request a material test report to confirm the optical glass grade and a scratch-dig inspection under ISO 10110 standards to ensure compliance with the listed tolerances.
