The EFL 4 mm Collimator Lens with an M9 × 0.5 thread is offered by Changchun Sunday Optoelectronics Co., Ltd. It has a clear aperture of 4 mm, making it suitable for compact optical assemblies. The lens is designed for high light transmission, delivering more than 95 % throughput in the visible range. It meets ISO 9001 standards, indicating compliance with recognised quality management practices.
The optical element is typically fabricated from BK7 crown glass, a common material for precision lenses. An anti‑reflection coating is usually applied to reduce surface reflections to below 1 %. Surface figure accuracy of λ/10 is standard for this class of collimator, ensuring minimal wavefront error. The finished part weighs roughly 0.5 g and is supplied with a polished surface finish.
Typical applications include laser beam shaping, scientific instrumentation, and imaging devices used in research laboratories, medical equipment manufacturing and telecommunications. Buyers often request bulk quantities, with flexible minimum order quantities and shipping under FOB or CIF terms. Payment is commonly arranged via L/C or T/T, and each lens is individually packaged to protect optical performance during transit.

Before placing an order, confirm the exact aperture, thread size and transmission values with the supplier and request the ISO 9001 certificate to verify compliance with recognised quality standards. Verify that the lens material is BK7 glass and that the anti‑reflection coating meets your system’s wavelength requirements.
Logistics should be clarified early: ask the supplier to confirm lead‑time, preferred Incoterms such as FOB or CIF, and the payment method (L/C or T/T). Packaging is typically individual sealed boxes with protective cushioning; request details on the packing list to ensure safe transport.
For quality assurance, arrange a pre‑shipment inspection that includes dimensional checks, transmission measurement and visual inspection of coating integrity. Request a test report or certificate of analysis for each batch, and confirm that the supplier can provide traceability documentation for regulatory compliance.
