Import 25mm Lens C-Cs Mount Lens Adapter — Buy in wholesale FOB from Supplier in China

This 25mm C-CS mount lens adapter is a precision spacer ring manufactured by Shenzhen Weikexiu Technology Co., Ltd. in Shenzhen, Guangdong Province. The adapter bridges the mechanical and optical gap between C-mount lenses and CS-mount cameras, industries where back focal distance compatibility determines image sharpness. Constructed from black anodised aluminium, the ring measures 25mm in outer diameter and adds 5mm to the optical path, the exact difference between the 17.526mm C-mount flange distance and the 12.526mm CS-mount standard. This dimensional precision ensures that lenses designed for the longer C-mount register achieve correct infinity focus when used on CS-mount machine vision or CCTV cameras. The component ships as a single adapter ring in standard packaging, with customisation available upon negotiation with the supplier.

The aluminium material selection provides lightweight rigidity and corrosion resistance, with the black anodised finish serving the dual purpose of durability and stray light suppression within the imaging path. The 25mm outer diameter matches common lens barrel dimensions in compact machine vision systems, though buyers should verify inner thread specifications against their specific lens and camera combinations. The adapter employs the 32 tpi Unified Thread Standard, typical for both C and CS mounts, ensuring mechanical compatibility across Japanese, European, and Chinese camera and lens manufacturers. Surface flatness and thread concentricity are critical quality parameters for adapters of this type, as any deviation introduces tilt or decentering that degrades image resolution, particularly at short working distances and wide apertures. Shenzhen Weikexiu does not publish runout or surface roughness tolerances in the source data, so these should be requested for precision applications.

Primary buyers include system integrators in machine vision, automated optical inspection, medical imaging, and security CCTV who need to repurpose existing C-mount lens inventories on newer CS-mount camera bodies. The adapter also finds use in microscopy, where 25mm is a common tube diameter, though the listing specifies CC.TV and general camera applications rather than research microscopy. Shenzhen Weikexiu operates from the Juguang E-Commerce Industrial Park in Longgang District, placing it within the broader Shenzhen electronics manufacturing ecosystem. The zero percent response rate in marketplace data suggests buyers should initiate contact to confirm current stock status, minimum order quantities, and any volume pricing before finalising procurement plans.

Shenzhen Weikexiu Technology Co., Ltd. is located at Juguang E-Commerce Industrial Park, Building 8, No. 9 Qilin Road, Bantian Street, Longgang District, Shenzhen, 518116, China. The company holds a Harbor trust tier classification, with marketplace data showing a zero percent response rate and zero average response hours. This profile may reflect a recently established trading office or a cataloguing approach to marketplace presence rather than operational unreliability, but buyers should not assume rapid quotation turnaround without testing communication directly. The address places the firm in one of Shenzhen's established industrial zones with ready access to CNC machining, aluminium finishing, and electronics assembly subcontractors.

The supplier's product focus appears to be optical and imaging accessories, with this C-CS adapter representing a standardised, commodity-type component rather than a proprietary design. No information is provided about factory ownership, QC staff levels, ISO certification, or years in operation, so claims about manufacturing depth cannot be independently verified from the source. The packaging description suggests individual polybag or blister pack presentation typical of accessory retail, with customisation possible for larger orders. Buyers requiring traceability documentation, material certificates, or dimensional inspection reports should specify these requirements in their initial enquiry to determine the supplier's quality management maturity.
