Import 2.8mm F2.0 Manual Iris Pinhole Lens — Buy in Bulk from Supplier in China

This 2.8mm f2.0 manual iris pinhole lens from Fujian Institute Of Optical Technology is a precision optical component engineered for detailed imaging in constrained spaces. Its 2.8mm focal length provides a wide 92-degree diagonal field of view, while the fast f/2.0 aperture ensures strong light transmission for performance in lower-light environments. The lens construction uses thirteen glass elements to minimise distortion and maintain image sharpness across the frame.

The manual iris mechanism allows the user to adjust the aperture directly, offering precise control over depth of field and exposure in variable lighting. This is a critical feature for applications where automated systems cannot reliably adapt. Typical industry specifications for such lenses include a minimum object distance around 0.2 metres, enabling close-up detail capture, and a compact form factor designed for integration into security housings or industrial equipment. The glass element count is notably high for a pinhole lens, which generally improves optical clarity and reduces chromatic aberration.

Buyers sourcing this lens are typically in the surveillance, robotics, or machine vision sectors, where its compact size and manual adjustability are valued. It is commonly integrated into covert security cameras, automated inspection systems, and specialised scientific equipment. For trade terms, the listing mentions flexible MOQs and FOB or CIF shipping options, but specific pricing, lead times, and certification availability (such as ISO) must be confirmed directly with Fujian Institute Of Optical Technology, as these details are not provided in the listing data.

Fujian Institute Of Optical Technology is based at No.18 Chayuan Road, Fuzhou 350013, China. The supplier profile indicates an 'imported' tier status within the platform's verification system, which typically signals a manufacturer or established trading entity. However, the listing does not provide additional details about the company's history, production scale, or specific client portfolio.

The supplier's response rate is listed as 0.00%, with an average response time of 0 hours, which suggests no recorded buyer inquiries on this platform to date. This does not reflect on the product's quality but highlights that initial communication may require patience. Prospective buyers should note that while the product description references potential ISO certifications and flexible trade terms, these are not confirmed in the listing and must be verified directly with the supplier during sourcing negotiations.
