Import Double Concave Lens — Buy in Bulk from Supplier in India

The Double Concave Lens is an optical element with two inward-curving surfaces, designed to diverge incoming light rays. It is manufactured from optical-grade plate glass, polished to minimize surface irregularities and achieve precise focal characteristics. The lens is available in two standard sizes: 50 mm and 75 mm diameter, with focal lengths of 5 cm and 10 cm respectively, as specified in the product listing.

The lenses are edge-ground to a tolerance of ±0.1 mm and have a surface quality of 60-40 scratch-dig, typical for educational and basic lab applications. The material is crown glass, with a refractive index of approximately 1.52 and Abbe number around 59, suitable for minimizing chromatic aberration in low-power optical systems. These lenses are not coated and are intended for use in non-critical optical setups such as beam expanders, projection systems, or introductory physics demonstrations.

This lens is commonly purchased by educational institutions, vocational training centers, and small-scale optical labs in developing regions. Buyers typically order in quantities of 10 to 100 units for classroom use. Packaging is in individual cardboard boxes with foam inserts. Delivery is arranged via air or sea freight from Ankleshwar, Gujarat, with Incoterms typically FOB Mumbai port. No certification documents are provided with the product.

Jay Shree Khodiyar Lab Equipment is a trading entity based in Ankleshwar, Gujarat, with a registered address at Yogi Estate, Plot No. 93. The supplier is verified at harbor level, indicating basic export compliance but no independent manufacturing certification. There is no information provided about laboratory accreditation, optical testing equipment, or in-house production capabilities. The listing does not mention years of operation, staff size, or client references.

The supplier has no recorded response rate or average response time, suggesting minimal engagement with buyers. No technical documentation, calibration certificates, or material test reports are referenced. Buyers should assume this supplier acts as a distributor of generic optical components sourced from third-party manufacturers, and should request physical samples before bulk purchase to verify optical performance.
