BK7 Fused Silica Ball Quartz Glass Ball LensJGS1
This BK7 fused silica ball lens from Sjl Laser combines BK7 borosilicate glass with JGS1 grade fused silica, offering transmittance from 200 nm to 2.2 µm and low thermal expansion. The spherical design simplifies system integration, making it ideal for fiber optic coupling, laser focusing, and spectroscopy. The lens is available in custom specifications, with fused quartz providing exceptional UV to near-IR performance for demanding applications.
BK7 is selected for cost-sensitive visible-range systems where optical homogeneity and broad transmittance are priorities, while JGS1 fused silica extends performance into UV and IR ranges. Typical applications include semiconductor inspection, medical endoscopy, and bar code scanning, where compact, high-precision optics are required. The lens’s low coefficient of thermal expansion ensures stability in environments with temperature fluctuations.
Importers in semiconductor, medical device, and research instrumentation industries source these lenses in bulk for OEM integration. The spherical geometry improves signal coupling between optical fibers, transmitters, and detectors, while hemispherical variants further simplify system design. Buyers should confirm material composition and spectral performance for their specific wavelength requirements.

Sourcing BK7 Fused Silica Ball Quartz Glass Ball Lens JGS1 from Sjl Laser - China Import Guide
Before placing an order, confirm the lens material composition (BK7, JGS1, or a combination) and its spectral performance for your application’s wavelength range. Verify the sphericity and surface quality tolerances, as these directly impact optical performance in beam shaping or coupling systems. Request sample lenses for prototype testing if your application has unique requirements.
Clarify packaging standards for optical components, which should include anti-static, foam-lined containers to prevent scratching or contamination during transit. Discuss lead times for custom diameters or materials, as these may require additional processing. Incoterms like FOB Shenzhen are common, with payment terms often structured as a 30% deposit and 70% balance prior to shipment to mitigate risk.
Insist on quality documentation, including material certifications for BK7 and JGS1, surface quality test reports, and sphericity measurements. For critical applications, arrange third-party testing for transmission spectra, thermal stability, or laser damage threshold. Ensure the supplier provides traceability for the fused silica or BK7 material to confirm it meets industry standards for optical homogeneity and purity.
