Low Distortion Lens – S12011803420F

S12011803420F-12mm F2.0 Low Distortion Lens, 8MP M12 fixed-focus manual-adjustment lens

12mm 8MP M12 Low Distortion Machine Vision Lens

This 12mm 8MP M12 low distortion lens is designed for compact machine vision and industrial imaging systems that require accurate image reproduction and a controlled field of view. With a 1/1.8″ sensor format, 42° diagonal FOV, <2% distortion, F2.0 aperture, and M12x0.5 mount, it provides a practical balance between image detail, optical stability, and compact system integration.

Product Core Highlights

• 8MP resolution: Supports high-detail imaging for modern 1/1.8″ vision sensors.
• Low distortion performance: <2% distortion helps preserve object shape and measurement consistency across the image.
• 12mm fixed focal length: Provides a controlled 42° diagonal FOV for applications requiring a more focused view than wide-angle lenses.
• F2.0 aperture: Provides a useful balance between light transmission, image brightness, and optical performance.
• Compact M12x0.5 mount: Suitable for space-constrained cameras, embedded vision systems, and compact industrial imaging equipment.

Low Distortion Lens Applications

The 12mm focal length and relatively narrow 42° diagonal field of view make this lens suitable for vision systems that need to observe a defined working area without excessive peripheral coverage. Its <2% distortion performance is particularly useful where geometric consistency is more important than ultra-wide scene coverage.

Designed for compact machine vision inspection applications, the lens can be integrated into inspection cameras used for component positioning, dimensional checking, surface inspection, and localized defect detection. The 8MP resolution helps capture fine image details while the 12mm focal length provides a controlled imaging area.

It is also suitable for robotic vision and automated equipment, where cameras need to monitor a specific working zone such as a conveyor section, assembly station, or robot operating area. The manual focus configuration allows the optical system to be adjusted during installation according to the working distance.

For industrial imaging projects requiring consistent optical performance, this lens can be combined with TOWIN’s Machine Vision solutions and other industrial optical configurations.

Typical compatible devices and systems include:

• Compact machine vision cameras
• Embedded industrial cameras
• Automated optical inspection equipment
• Robotic vision cameras
• Conveyor inspection cameras
• Component inspection systems
• Positioning and alignment cameras
• Smart industrial cameras
• Compact AI vision devices

The 0.15m minimum object distance also provides flexibility for relatively close-range inspection tasks where the camera must be positioned near the target.

Frequently Asked Questions

Q: What type of lens is this 12mm lens?
A: It is an 8MP M12 fixed focal lens with low distortion performance, designed primarily for compact machine vision and industrial imaging applications.

Q: Is this a low distortion lens?
A: Yes. The specified distortion is below 2%, making it suitable for applications where maintaining the shape and geometry of objects in the image is important.

Q: What sensor size is this M12 lens designed for?
A: The lens is designed for a 1/1.8″ image format with a maximum image circle of approximately Φ11mm.

Q: What is the field of view of the 12mm lens?
A: On a 1/1.8″ sensor, the lens provides a 42° diagonal, 34° horizontal, and 25.5° vertical field of view.

Q: Is the focus adjustable?
A: Yes. The lens uses manual focus, allowing the imaging system to be adjusted for the actual working distance during installation.

Q: What does the IRCF structure mean?
A: IRCF refers to an IR cut filter structure. It helps block infrared wavelengths in visible-light imaging systems and should not be confused with an optically IR-corrected lens.

Q: Is this lens suitable for machine vision cameras?
A: Yes. Its 8MP resolution, <2% distortion, 12mm focal length, F2.0 aperture, and M12x0.5 mount make it well suited to compact machine vision and industrial imaging cameras.

Q: Can TOWIN customize this M12 lens for a specific project?
A: Yes. TOWIN can support customized optical and mechanical configurations for OEM and ODM projects, depending on sensor, field of view, mounting, working distance, and environmental requirements.

Learn More About Industrial Lens Selection

Selecting the right industrial lens requires matching the focal length, sensor size, field of view, distortion, resolution, and working distance to the camera system. TOWIN’s Lens Selection Guide can help engineers evaluate these parameters before choosing an optical configuration.

For projects requiring a specific field of view or working distance, the FOV Calculator can also be used as a preliminary lens-selection tool.
