2/3 Fixed-Focus C-Mount Lens 25mm F2.8-16 Manual Adjustable Iris Ultra-Low

OKS-FA-3225-281A is a high-performance fixed-focus FA industrial C-mount lens, specially developed for machine vision inspection, factory automation, surface defect detection and high-precision dimensional measurement systems.

Designed for 2/3-inch industrial CMOS/CCD sensors, it delivers excellent imaging performance. The manual adjustable iris (F2.8-16) with locking design can effectively lock the aperture position, preventing parameter drift caused by mechanical vibration on the production line. Ultra-low distortion <=0.2% at 300mm working distance and high MTF performance 145LP/mm >=0.2 guarantee highly accurate measurement and defect detection results.

The 4G all-glass optical structure provides high light transmittance, with relative illuminance >=75%, ensuring clear and uniform imaging across the entire field of view. Equipped with M27*P0.5 filter thread, users can install various optical filters to adapt to complex on-site lighting conditions. The wide working distance range of 90mm to 1500mm provides multiple magnification options to meet different installation distance requirements. The rugged all-metal anti-vibration structure ensures stable long-term operation, widely used in electronic component inspection, PCB surface inspection, robot visual guidance and automated quality control OEM mass production.
