C-Mount 20MP Industrial FA Lens 16mm F2.8-11 1.1 Large Format Manual Iris Focus Low Distortion

OKS-FA-1016-2811 is high-performance 20MP fixed-focus FA industrial C-mount lens, specially developed for machine-vision inspection, factory automation, defect detection and dimensional measurement systems.

Designed for 1.1-inch large-format image sensor, it delivers outstanding 20MP resolution across full image area. Manual adjustable iris (F2.8-11) and locking focus ring allow flexible aperture & focus setting for different working distance scenarios. Ultra-low distortion <=-0.35% at 350 mm working distance guarantees high-precision measurement results for industrial visual inspection.

Built-in M30.5*P0.5 filter thread supports installation of various optical filters to adapt complex lighting condition on production line. Multi-layer broadband anti-reflection coating greatly improves light transmittance and suppress ghost and stray-light interference. Wide working distance from 100 mm to 1000 mm meets diverse installation requirement. All-metal rugged housing with anti-vibration mechanical design ensures stable long-run performance for automated production equipment OEM mass-production.
