Low Distortion Lens – S20013001360F

S20013001360F is Low-distortion 1/3″ M12 CCTV lens with 3-Megapixel, 20mm focal length, and 17° diagonal field of view Suitable for security Surveillance.

20mm 3MP M12 Low Distortion Lens

This 20mm M12 industrial lens is designed for 1/3″ 3MP image sensors and applications requiring a narrow, controlled field of view. With less than 0.5% distortion, a fixed F6.0 aperture, and a 0.3m minimum object distance, it provides stable imaging for compact machine vision, embedded inspection, and fixed-target industrial cameras.

Product Core Highlights

• 20mm fixed focal length for narrow-area target imaging.
• <0.5% distortion for controlled image geometry.
• 3MP resolution for detailed industrial image capture.
• 0.3m M.O.D. for close-to-medium working distances.
• M12 × 0.5 mount for compact embedded camera integration.

20mm M12 Low Distortion Lens Applications

Core Application Scenes

This 20mm 3MP M12 low distortion lens is designed for imaging systems that need to concentrate the camera view on a specific target area. Its 17° diagonal FOV and 20mm focal length provide substantially narrower coverage than wide-angle M12 optics, making it useful when the target occupies a defined portion of the scene and unnecessary background coverage needs to be minimized.

The lens is well suited to fixed-position inspection and localized object monitoring. Its distortion specification below 0.5% helps maintain controlled image geometry, which can be valuable for visual inspection tasks involving component edges, object positioning, surface features, and image-based classification.

With a fixed F6.0 aperture, the lens is particularly appropriate for installations where the lighting conditions are controlled and consistent. The 0.3m minimum object distance also makes it suitable for applications where the camera is positioned at a short-to-medium distance from the inspection target rather than directly against the object.

The M12 × 0.5 interface allows the lens to be integrated into compact camera modules where installation space is limited. For engineers developing a dedicated embedded vision system, the M12 Lenses range provides additional optical configurations for comparison.

Compatible Device List

• Compact Industrial Cameras: Suitable for 1/3″ 3MP camera modules requiring a relatively narrow field of view.
