OKS-FA-3216-2811 is high-performance 12MP 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 CMOS/CCD industrial sensor, it delivers full-format 12MP high-definition imaging. Manual adjustable iris (F2.8-11) and locking-type focus ring can lock aperture and focus position effectively, preventing parameter offset caused by mechanical vibration on production-line. Low distortion <=-0.9% at 300 mm WD, excellent MTF performance >=145lp/mm@0.2 and high relative illumination >=94% guarantee reliable measuring and defect-detection results.
Equipped with M27*P0.5 filter thread, users can install various optical filters for complex on-site lighting. Wide working-distance range 80-1490 mm provides multiple magnification choices to satisfy diverse installation-distance requirements. Rugged all-metal anti-shock mechanical structure guarantees stable long-term operation. Widely used for electronic component inspection, PCB surface checking, robot visual guidance and automated quality-control OEM mass-production.
