Bk7 K9 Jgs1 Meniscus Lens, Bi Convex Lens
The Bk7 K9 Jgs1 Meniscus Lens, Bi Convex Lens offered by Changchun Sunday Optoelectronics Co., Ltd is manufactured from BK7 optical glass with optional CaF2 or sapphire substrates. The lens is supplied in diameters ranging from 0.1 mm to 600 mm, covering most industrial size requirements. Surface quality is specified as 10/5 scratch‑dig, and flatness is held to 1/10 λ (λ = 550 nm). Anti‑reflection (AR) or broadband AR (BBAR) coating can be applied upon request.
BK7 glass provides a refractive index of approximately 1.5168 at the standard 587.6 nm wavelength and an Abbe number near 64, making it suitable for visible‑light applications. When a lower dispersion is needed, CaF2 offers an index around 1.434 and a higher Abbe number, while sapphire delivers superior hardness for harsh environments. Typical thickness tolerance for precision lenses of this class is ±0.05 mm and diameter tolerance is ±0.1 mm, aligning with industry practice. The supplied surface quality of 10/5 meets the ISO 10110‑2 standard for optical components.
These lenses are commonly integrated into laser collimators, imaging systems, and medical instrumentation where tight focus and minimal aberration are required. OEM manufacturers and research laboratories order them in bulk, often specifying custom diameters and coating types. The supplier states that bulk orders can include AR or BBAR coating on request and that shipping terms such as Incoterms and payment method are negotiable; buyers should confirm minimum order quantities, lead time, and any certification documents directly with the supplier.

Sourcing Bk7 K9 Jgs1 Meniscus Lens, Bi Convex Lens from Changchun Sunday Optoelectronics Co., Ltd - China Import Guide
Before placing an order, verify the exact material and substrate choice, ensuring that the BK7, CaF2 or sapphire option matches the optical performance required for your application. Request a material data sheet that lists the refractive index, Abbe number and transmission curve, and confirm that the surface quality and flatness meet the 10/5 and 1/10 λ specifications stated. Any deviation from these parameters should be documented in the purchase agreement.
Discuss logistics early by confirming the preferred Incoterm, typical lead time for custom diameters, and the payment method such as Letter of Credit that the supplier accepts. Because the supplier’s response rate is recorded as zero, maintain a written record of all communications and request a production schedule before the order is confirmed. Clarify whether the supplier can provide inspection reports, such as interferometric flatness measurements, and whether third‑party quality audits are possible.
Arrange for an independent inspection either pre‑shipment or at the destination port to verify surface quality, coating integrity and dimensional tolerances. Ask the supplier to supply a certificate of conformity and any test data that demonstrate compliance with ISO 10110‑2. By securing these documents and confirming the packaging method, you reduce the risk of receiving lenses that do not meet the required optical standards.
